in thread Functional Programming & method rewriting

Hmm, I did go the long way to do it, didn't I? :)
Thanks for the idea.

sub foo { print "hi mom\n"; my $ptr = \&foo; *foo=sub { print "that was unneccessary:"; $ptr->(); }; } foo(); foo();

Hmm, more Perl voodoo. I like it.

    Using your subroutine, try running
    foo(); foo(); foo(); foo();
    or for the really dangerous,
    foo() for (1..1000);
