Great.

A pity you don't cache the possibility that it doesn't exist:

BEGIN { my %cache; sub do_it { my $func = shift; $cache{$func} = do { local @ISA; __PACKAGE__->can("do_$fun") } unless exist $cache{$func}; $cache{$func}->(@_); } }

Update: merlyn is right. Fixed that.

    BEGIN { my %cache; sub do_it { my $func = shift; $cache{$func} = do { local @ISA; __PACKAGE__->can("do_$fun") } unless defined $cache{$func}; $cache{$func}->(@_); } }
    This does precisely what mine does. Did you mean "exists" there instead of "defined"?
