Page "CPAN" Paragraph 38

Beyond April Fools ', however, some of the distributions on the CPAN are jokes in themselves.

The Acme :: hierarchy is reserved for joke modules ; for instance, Acme :: Don't adds a function that doesn't run the code given to it ( to complement the built-in, which does ).

Even outside the Acme :: hierarchy, some modules are still written largely for amusement ; one example is Lingua :: Romana :: Perligata, which can be used to write Perl programs in a subset of Latin.
