Don't use an abstract base class; use roles...

{ package IAmNotInYourIsa; use Moose::Role; requires 'dothis'; } { package My::CGI; use Moose; with 'IAmNotInYourIsa'; use CGI; sub dothis { ... my $q = CGI->new ... $q->param ... } } My::CGI->isa('IAmNotInYourIsa'); # false My::CGI->does('IAmNotInYourIsa'); # true!

A good example can be seen in the Ask distribution on CPAN, where there are different implementations for STDIN/STDOUT, Tk, etc, each of which include:

with 'Ask::API';

Ask uses Moo rather than Moose, but the principle is the same.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
