Thanks for the report -- since you refactored this code yourself recently I presume you know where to fix it!

I'm working on a fix for this and #2124.

The same error is reported for typing.NamedTuple, which supports arbitrary named parameters. Will the fix for collections.namedtuple address typing.NamedTuple?

#4788 depends on this so raising priority to high.

Fixed by #5215.
