...and, most importantly, cleverly morphed into an efficient implementation
behind the scenes. We're supposed to be making Perl o-o *more* efficient,
not adding more subroutine calls. Convenience and performance should
not always have to be mutually exclusive.

The operative word being "cope" ;) Also, I tend to write many more methods
than I do autoloaders (YMMV), so I'd almost definitely use an efficient,
convenient, implicit "self" bareword or scalar, whereas I'd probably just
stick with $AUTOLOAD the few times I have to use it.
