This is actually a pretty huge deal! The import of pkg_resources is pretty expensive. It amounts to something like 20% of the overhead of my test runner hammett when using this plugin!

Yeah, importing/using pkg_resources just for this is really bad after all. pytest should probably have a version_info tuple.

I'll look into removing this separately already.

@boxed done, thanks for pointing it out!

@boxed as for performance in pytest itself see pytest-dev/pytest#4376.
I might take this into blueyed/pytest soon, you might want to try adding your "test case" / scenario there already.
