I think you've misunderstood what Modern::Perl is. It's basically a pragma equivalent to use strict, use warnings, and a couple other "modern" things, all lexically scoped. So if foo isa bar and bar uses Modern::Perl, there is no effect on foo.
But the question is how to make your own "pragma" that does what Modern::Perl does, presumably plus some other things.
