[issue9232] Allow trailing comma in any function argument list.

[Guido van Rossum]

Guido van Rossum added the comment:

I'm +1 on adding this. I don't believe it requires a PEP. A trailing comma in definitions is already supported in some places, so I don't buy the argument that it catches errors. During the moratorium we were perhaps too strict.
