[New-bugs-announce] [issue23161] collections.abc.MutableSet missing methods

[Devin Jeanpierre]

New submission from Devin Jeanpierre:

>>> set(dir(set)) - set(dir(collections.abc.MutableSet))
{'copy', 'update', '__rsub__', 'union', 'issubset', 'intersection', 'issuperset', '__rxor__', 'difference', 'symmetric_difference', 'difference_update', '__rand__', 'intersection_update', 'symmetric_difference_update', '__ror__'}

Most of these should be implemented on MutableSet rather than subclasses.
