Content
I think a more general facility to strip unwanted frames from traceback objects would be useful for more people (including importlib, I think). i.e. actually mutate the traceback object, not remove the unwanted frames when printing (since it only works if you're the one doing the printing). (note mutating a traceback object is very easy in C, it's just not possible in pure Python, except perhaps with nasty ctypes hacks) Also, the `ignore_modules` would be more powerful as a generic `filter` callback, I think.
