Problem is, its extremely difficult to figure out what module
implements what. Sure, if you see a C<sub foo {...}> you have a
pretty good idea that foo() is implemented, but there's all sorts of
not uncommon tricks which make lexical scanning for subroutines nigh
impossible. Consider Class::Accessor, Class::Class or
Class::MethodMaker (those are for methods, which are not important,
but the same technique works for funcitons). Or even CGI.pm's brand
of autoloading (using strings in a hash instead of the usual
subroutines after __END__).

Plus I remember being impressed with Ada because you could write an
infinite loop without a faked up condition. The idea being that in Ada
the typical infinite loop would be normally be terminated by detonation.
