Additional constructs in gnu.expr

[Daniel Bonniot]

gnu.expr currently holds classes to generate code for functional
languages a la Scheme. As a part of my Nice compiler
( http://nice.sourceforge.net ) if have written a few expression classes
to generate code for some imperative features: for and while loops, pre
and post incrementation of variables (a la 'x++'), lauching an
exception.
I was carefull to make them generate reasonably good bytecode.

My question: do they belong to gnu.expr, or should I place them in a
personal package? I think they could be useful to people using gnu.expr
to generate java bytecode for other imperative languages.
