Summary
__mapfeels like a reference to the pre-PEP-570 convention for specifying positional-only parameters. But this parameter is already clearly denoted as positional-only without that, because of the fact that it appears before the/in the parameter list. I thinkmapis a clearer name hereTest Plan
