I wonder if nowadays the error message shouldn't be updated to something "requires explicit package name or lexical "my" declaration ..."
Lexicals replaced package vars as a standard long ago, maybe the feedback should reflect the most probable cause.
I'm aware that changing the message might confuse some parsers, but it's such a common question here that it's worth a rethink.
