No - this doesn't work as
#define bar (printf ("Evil side effect"), 42)
is perfectly legal. So, we have an implicit IO monad here,
too. What is interesting, however, is that C does not
require `return' in all contexts itself. Or in other words,
C's comma notation has an implicit `return' in the last
expression.

That's a good one, however. It in effect rules out side
effects by C's definition of constant expressions.
So, I guess, I have to extend my example to
bar x = x + 42
Cheers,
Manuel
