Hi, During the Language Summit 2011 (*), it was discussed that PyPy and Jython don't support non-string key in type dict. An issue was open to emit a warning on such dict, but the patch has not been commited yet.
I'm trying to Lib/test/crashers/losing_mro_ref.py: I wrote a patch fixing the specific issue (keep a strong reference to the MRO during the lookup, see #14199), but I realized that the real problem is that we allow custom objects in the type dict. So my question is: what is the use case of such dict? Why do we still support it? Can't we simply raise an error if the dict contains non-string keys?
