The fact that this question has to be asked at all and the contortions necessary to answer it points to a deficiency in Perl's semantics. The following code
thatroutine() and return;
would be simple and effective were it not for the fact that a
return with no argurments is equivalent to
return undef (or
return () in list context). By making the
undef or
() mandatory in order to clear the "last expression evaluated" this whole discussion could have been avoided.
