in thread Template Method contra passing subroutines to constructor.

I meant two different modules that want to use the same sub ref.

    Hmm, in that case you might be constrained by your design, but it is still possible like this:

    package Foo;
sub filter 
{
    . . . 
}

package Bar;

my $obj = Baz->new( \&Foo::filter );

    Admittedly, this could get hackish fast.

      That would work, but by then there's no advantage to sub refs over inheritance. You are basically hard-coding inheritance here.
