My off the cuff feeling is that this is a good idea.  I have often wished
for something like this, particularly when trying to write complicated
macro expressions with lots of side effects (and better off written
as functions, to boot! :-) )   (Remember the pascal to c translator posted
to comp.sources.unix last summer?  Anyone notice that the code for terminal
IO was totally wrong?  The reason was that the author used the "," operator
as if it behaved like ",," in several places.)

Naturally I expect the reply to this suggestion is going to be "try C++".
