-@deffn {Scheme Procedure} environment-fold env proc init
-@deffnx {C Function} scm_environment_fold (env, proc, init)
-Iterate over all the bindings in @var{env}, accumulating some

-For each binding in @var{env}, apply @var{proc} to the symbol
-bound, its value, and the result from the previous application
-of @var{proc}.
-Use @var{init} as @var{proc}'s third argument the first time
-@var{proc} is applied.
-If @var{env} contains no bindings, this function simply returns

-If @var{env} binds the symbol sym1 to the value val1, sym2 to

-Bind @var{sym} to a new location containing @var{val} in

-@deffn {Scheme Procedure} environment-cell env sym for_write
-@deffnx {C Function} scm_environment_cell (env, sym, for_write)
-Return the value cell which @var{env} binds to @var{sym}, or
-@code{#f} if the binding does not live in a value cell.
-The argument @var{for-write} indicates whether the caller
-intends to modify the variable's value by mutating the value
-cell. If the variable is immutable, then
-@code{environment-cell} signals an
-@code{environment:immutable-location} error.
-If @var{sym} is unbound in @var{env}, signal an
-@code{environment:unbound} error.
-If you use this function, you should consider using

-@deffn {Scheme Procedure} environment-observe env proc
-@deffnx {C Function} scm_environment_observe (env, proc)
-Whenever @var{env}'s bindings change, apply @var{proc} to

-@deffn {Scheme Procedure} environment-observe-weak env proc
-@deffnx {C Function} scm_environment_observe_weak (env, proc)
-This function is the same as environment-observe, except that
-the reference @var{env} retains to @var{proc} is a weak
-reference. This means that, if there are no other live,
-non-weak references to @var{proc}, it will be

-@end deffn
-
-@deffn {Scheme Procedure} environment-unobserve token
-@deffnx {C Function} scm_environment_unobserve (token)
-Cancel the observation request which returned the value

-@deffn {Scheme Procedure} make-eval-environment local imported
-@deffnx {C Function} scm_make_eval_environment (local, imported)
-Return a new environment object eval whose bindings are the
-union of the bindings in the environments @var{local} and
-@var{imported}, with bindings from @var{local} taking
-precedence. Definitions made in eval are placed in @var{local}.
-Applying @code{environment-define} or
-@code{environment-undefine} to eval has the same effect as
-applying the procedure to @var{local}.
-Note that eval incorporates @var{local} and @var{imported} by
-reference:
-If, after creating eval, the program changes the bindings of
-@var{local} or @var{imported}, those changes will be visible
-in eval.
-Since most Scheme evaluation takes place in eval environments,
-they transparently cache the bindings received from @var{local}
-and @var{imported}. Thus, the first time the program looks up
-a symbol in eval, eval may make calls to @var{local} or
-@var{imported} to find their bindings, but subsequent
-references to that symbol will be as fast as references to
-bindings in finite environments.
-In typical use, @var{local} will be a finite environment, and
-@var{imported} will be an import environment

-
-@deffn {Scheme Procedure} make-import-environment imports conflict_proc
-@deffnx {C Function} scm_make_import_environment (imports, conflict_proc)
-Return a new environment @var{imp} whose bindings are the union
-of the bindings from the environments in @var{imports};
-@var{imports} must be a list of environments. That is,
-@var{imp} binds a symbol to a location when some element of
-@var{imports} does.
-If two different elements of @var{imports} have a binding for
-the same symbol, the @var{conflict-proc} is called with the
-following parameters: the import environment, the symbol and
-the list of the imported environments that bind the symbol.
-If the @var{conflict-proc} returns an environment @var{env},
-the conflict is considered as resolved and the binding from
-@var{env} is used. If the @var{conflict-proc} returns some
-non-environment object, the conflict is considered unresolved
-and the symbol is treated as unspecified in the import
-environment.
-The checking for conflicts may be performed lazily, i. e. at
-the moment when a value or binding for a certain symbol is
-requested instead of the moment when the environment is
-created or the bindings of the imports change.
-All bindings in @var{imp} are immutable. If you apply
-@code{environment-define} or @code{environment-undefine} to
-@var{imp}, Guile will signal an
- @code{environment:immutable-binding} error. However,
-notice that the set of bindings in @var{imp} may still change,
-if one of its imported environments changes.

-@deffn {Scheme Procedure} make-export-environment private signature
-@deffnx {C Function} scm_make_export_environment (private, signature)
-Return a new environment @var{exp} containing only those
-bindings in private whose symbols are present in
-@var{signature}. The @var{private} argument must be an
-environment.
-
-The environment @var{exp} binds symbol to location when
-@var{env} does, and symbol is exported by @var{signature}.
-
-@var{signature} is a list specifying which of the bindings in
-@var{private} should be visible in @var{exp}. Each element of
-@var{signature} should be a list of the form:
- (symbol attribute ...)
-where each attribute is one of the following:
-@table @asis
-@item the symbol @code{mutable-location}
- @var{exp} should treat the
- location bound to symbol as mutable. That is, @var{exp}
- will pass calls to @code{environment-set!} or
- @code{environment-cell} directly through to private.
-@item the symbol @code{immutable-location}
- @var{exp} should treat
- the location bound to symbol as immutable. If the program
- applies @code{environment-set!} to @var{exp} and symbol, or
- calls @code{environment-cell} to obtain a writable value
- cell, @code{environment-set!} will signal an
- @code{environment:immutable-location} error. Note that, even
- if an export environment treats a location as immutable, the
- underlying environment may treat it as mutable, so its
- value may change.
-@end table
-It is an error for an element of signature to specify both
-@code{mutable-location} and @code{immutable-location}. If
-neither is specified, @code{immutable-location} is assumed.
-
-As a special case, if an element of signature is a lone
-symbol @var{sym}, it is equivalent to an element of the form
-@code{(sym)}.
-
-All bindings in @var{exp} are immutable. If you apply
-@code{environment-define} or @code{environment-undefine} to
-@var{exp}, Guile will signal an
