in reply to Call Subroutines by Approximate Name
You could make some *really* obfuscated Perl with this sort of technique. Or, using the Lingua::Wordnet module (q.v. the Summer 2000 TPJ), you could call subroutines by their hypernym. To use an example from the article, you could call &sneaker and have it *really* call &loafer instead.
