I really don't think you understand how this works, but I don't know
how to explain it a different way.

Pattern matching and regexp matching are essentially the same, and both
are active in contexts where they're defined to be active.  Pattern
matching is a component of pathname expansion, and is active when and
where pathname expansion occurs.  I think you're concentrating too hard
on whether or not there's an `operator' present.
