and the type you're using doesn't allow undef, you're in a world of hurt.
lazy_required at all. All a class needs to do is say use MooseX::LazyRequire; and the clone_and_inherit_options method of Moose::Meta::Attribute will be wrapped - for *all* attributes.

This is a bug that was reported 8 years ago, and has been bugging me on-and-off for a while.
Basically, because _process_options isn't called if you're inheriting from another class, lazy_required wasn't getting applied in a sub-class. There was an initial test class supplied in the bug report that I've used as a base; I've updated some of the wording to (in my mind) make it clearer what we're trying to test.
