Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.

Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.

++dragonchild gave the precise answer to your question.
If the application you're thinking of is transparently wrapping existing code (i.e., have the method being redefined be called by that which redefines it), look at Hook::LexWrap. You may find Aspect interesting also. | [reply] |
