Didn::t know that. Thanks for letting us know.

Though it puts a crimp on Perl joke modules, there don::t appear to be enough of those to warrant keeping it -- the only one I remembered without googling was Chris Nandor's classic Do'h, released before the CPAN Acme namespace was born.

This is all I could find:

• Do'h by Chris Nandor
• D'oh::Year by Mick Schwern
• Acme::Don't by Damian Conway
• Test::More - this core module uses a typeglob alias (sub isnt { ... } *isn't = \&isnt) to allow you to write isn't in your tests instead of isnt ... hardly a critical feature. :)
