I've always thought is was pretty useful for implementing generic
redirectors. I wrote a frame system that allows instances to over-ride
class methods. The basic idea is
sub foo {
my $method = $_[0]{"_foo"} || $_[0]->can("_foo");
&{$method};
}
The only thing I'd like to change is to make &foo a tail call instead
of a normal function call. But I guess that would *really* confuse
people.
