At last night's London.pm birthday party, I somehow ended up discussing Acme::Current with 2shortplanks.
Mark mentioned an uncommitted patch he submitted Acme::Current that means the code to the module doesn't need updating daily, but still requires daily installation. Of course, you should never patch an Acme module to behave sensibly, in this case just report today's date.
We then got onto silly ideas about subclassing the module, to do things such as report tomorrow's date, and something sick involving $0 that I don't remember properly.
It fascinates me that people in close communities often come up with similar ideas at roughly the same time: zeitgeists and all that...
A while ago, I tried explaining the idea of Acme modules to non-Perl people, including non-programmers. I don't think anyone quite understood, including me.
