+ * boot-9.scm (module-make-local-var!): When creating a new
+ variable, initialize it to the value of any imported variable with
+ the given name. This allows code like (define round round) to
+ work as expected.

+ From Antoine Mathys <tonigonenstein@users.sourceforge.net>:
+
+ * popen.scm: Support bidirectional communication by making
+ open-pipe support OPEN_BOTH as second argument and in that case
+ return a soft input-output port which uses two pipes internally.
+ Provide open-pipe* to execute programs without using the shell
+ (and actually base open-pipe on it) and the obvious
+ open-input-output-pipe.
