sligthly related: I've been thinking if could be possibe a
-v<warn_level|warning_class*> that would set $VERBOSE to something
(i.e an hash ) instead of plain true.
This won't even break code with checks like 
if $VERBOSE.

This way, for example , one could still look for unreachable
statements but forget uninitialized variables, or enable warnings for
changes beetween 1.6 and 1.8, or 'for future version' warnings... 

or possibly this already happens ?
