I don't want to separate each class definition out into a a separate file.

If you were truly using classes, you wouldn't have this problem. You're not using classes. You're reinventing modules, and that badly.

Otherwise it adds unnecessary complexity.
use mem &{sub(){$::INC{'Dbg.pm'}=1}};

That's necessary complexity? Reimplementing something Perl already knows how to do for you—in an ugly and incomplete fashion—is both necessary and sufficiently simple?

Even the syntax use mem 'Dbg'; would be far less blepharitic—no less obnoxious, but at least it would keep the ugliness to only one spot in your code.
