[New-bugs-announce] [issue22998] inspect.Signature and default arguments

[Walter Dörwald]

New submission from Walter Dörwald:

inspect.Signature.bind() doesn't add values for parameters that are unspecified but have a default value. The documentation at https://docs.python.org/3/library/inspect.html#inspect.BoundArguments.arguments includes an example how to add default values, but that example doesn't work for the * and ** parameters.

This patch adds a new method Signature.bind_with_defaults() that works like Signature.bind(), but includes parameters with a default value (and can handle values for the * and ** parameters).
