Description
Feature or enhancement
Currently, call objects from the unittest.mock library only provide a tuple of positional arguments and a dictionary of keyword arguments passed to the function. It should be possible to enable accessing all arguments by name, not just the keyword arguments. The Signature object can help with this: https://docs.python.org/3/library/inspect.html#introspecting-callables-with-the-signature-object.
Pitch
For more robust and readable testing code.

Research direction
Start by reading the unittest.mock call-object behavior and the linked inspect.Signature documentation. Determine how accessing positional arguments by name should work alongside the existing positional tuple and keyword dictionary, then define the expected API and tests that demonstrate readable named-argument access.
