... and it automatically loads the parent module.

Sometimes.

base is a pretty unreliable module, in my experience, and it must be related to the heuristic method it uses to determine whether a module file needs to be loaded, or not. Sometimes, it guesses wrong.

update Apparently tye has had similar experiences.

Looking at the source, I don't see it doing anything except checking if the module is already in your @ISA. That seems pretty sane to me.	[reply]

It's checking `${"$package\::VERSION"}` or something to that effect, while a package is not required to have a `$VERSION` variable. Maybe its behavior has been sanitized, but the damage is done. My trust has been shaken.	[reply] [d/l] [select]

Hmm, none of my classes have $VERSION declarations, and base has never given me any trouble about it.	[reply]
