perlhack - How to hack at the Perl internals
- DESCRIPTION
-
Does concept match the general goals of Perl?, Where is the
implementation?, Backwards compatibility, Could it be a module instead?, Is
the feature generic enough?, Does it potentially introduce new bugs?, Does
it preclude other desirable features?, Is the implementation robust?, Is
the implementation generic enough to be portable?, Is the implementation
tested?, Is there enough documentation?, Is there another way to do it?,
Does it create too much work?, Patches speak louder than words
