I can't even access it to make a copy, can I? - no way of making %M::E::A::ENTITIES ?

Think of a "my" as similar to "private" data in Java (if I remember my Java, that is). It's pretty much totally inaccessable without using XS to violate the encapsulation and troll through the Perl guts directly. Your best bet may be to do a copy/paste into your subclass and modify it that way. Ugly hack and dependency, but probably the sanest alternative if you really need it.
