Feature or enhancement

Proposal:

Currently, _NamespacePath is prefixed as a private type, but since it's exposed, it should be marked as public API. I have a specific case in mind where I want to do an instance check.

I vaguely remember a discussion somewhere with @warsaw where this was mentioned, but I can't find it.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
