Nagging is one way to accomplish change, but it's sure annoying. If you feel
the feature is import, you know where to get the source. Give it a shot.
Contribution of code is oh so much more valuable than a constant stream of "you
should change..."
Repeatedly claiming that Walter ignores 'X' is another way to get a reaction,
but it's also very annoying. You're far from the only person to pull this card
out. Do you _honestly_ believe he's that narrow minded or are you just trying
to get enough of a rise out of such claims that he'll drop what he's doing and
focus on your nag-of-the-day?
Sigh.. it get's old, fast.
Back to lurk mode,
