* Lisp changes in Emacs 23.1

** New `function vector' type, including function currying
The `function vector', or `funvec' type extends the old
byte-compiled-function vector type to have other uses as well, and
includes existing byte-compiled functions as a special case.  The kind
of funvec is determined by the first element: a list is a byte-compiled
function, and a non-nil atom is one of the new extended uses, currently
`curry' for curried functions.  See the node `Funvec Type' in the Emacs
Lisp Reference Manual for more information.

*** New function curry allows constructing `curried functions'
(see the node `Function Currying' in the Emacs Lisp Reference Manual).

*** New functions funvec and funvecp allow primitive access to funvecs
