yes, you are right.
sorry for my previous reply with wrong infomation.

I didn't use `module` for very long. I don't remember what `module` exactly does.
I just vaguely recall it has something to do with `setfenv`.

but anyway, `module` is 5.1; I don't think checking the `_NAME` field is a reliable
solution for OP's problem.
