Looking at the gist, and specifically at the last section of it, I'm wondering why you can't just use the fully specified method name. I.e., instead of

    sub configure {
        my ($coderef) = sub {
            hello;
        };

do
    sub configure {
        my ($coderef) = sub {
            PackageA::hello;
        };

This is different from what normally happens in closures.

It sounds like you have some problem you're trying to decide, and you have gotten onto this particular path of solving it, and it's not really the right solution. Perhaps you could explain what you're trying to achieve with this code? (Not the "call a method in packageB but use packageA's context for method resolution", but the problem you were working on solving _before_ you started on this…)

 chrs,
john.
