Hi all, 

TXR 202 [1] is out. Binaries at Bintray [2]. 

	* This release features some optimizations in the compiler, virtual
machine and arithmetic library.
 	* A function called copy-fun is introduced

 	* it copies function objects, creating an independent copy of their
lexical environment

	* The copy receives a "snapshot" of the current values of the variable
bindings, and is then not affected by subsequent mutations of those
variables.

 	* BUGFIX: the compile function now properly handles functions that are
carrying a lexical environment.

 Cheers ...
