But you snipped the examples of void context. Things like:
chomp;
and
chomp($var);
while (chomp(<>)) { } gets magically changed (as previously described),
for(chomp(<>)) pulls in all the lines of <>, chomps each one and iterates over
the resulting list (actually, I hadn't thought about it before, but that' what
makes sense to me :-).

==========================================================
If a nonnegative quantity was so small that it is smaller than any given
one, then it certainly could not be anything but zero. To those who ask what
the infinitely small quantity in mathematics is, we answer that it is
actually zero. Hence there are not so many mysteries hidden in this concept
as they are usually believed to be. These supposed mysteries have rendered
the calculus of the infinitely small quite suspect to many people. Those
doubts that remain we shall thoroughly remove in the following pages, where
we shall explain this calculus.
-- Euler, Leonhard (1707 - 1783)
