[issue18244] singledispatch: When virtual-inheriting ABCs at distinct points in MRO, composed MRO is dependent on haystack ordering

[Guido van Rossum]

Guido van Rossum added the comment:

Ok, let's do it.  I just sent you a review of your latest code (admitting I don't actually follow the logic in full detail, so I'm mostly harping on tests and comments...).

Regarding the PEP: feel free to update this.  Clearly nobody read it this carefully before...  "Final" in the Python world doesn't mean "every typo remains forever" and for PEPs this young that also applies to esoteric details that were perhaps not fully, or not correctly, specified before.
