[New-bugs-announce] [issue15486] Standardise the mechanisms for stripping importlib frames

[Nick Coghlan]

New submission from Nick Coghlan:

Thanks to issue #15425, the number of special cases in the importlib frame stripping is growing. This patch tweaks the frame stripping mechanism to make it easy to selectively strip frames in importlib._bootstrap by creating a _call_with_frames_removed helper function.

The rules in remove_importlib_frames then change to remove any sequence of importlib frames which ends with that helper and all importlib frames in the ImportError case.
