As a secondary behavior here, which is actually the one that matters more for my use case, the following seems surprising as well: import inspect s = inspect.signature(lambda **kwargs: kwargs).bind() s.arguments["foo"] = 12 will similarly silently drop "foo" when attempting to call the function (i.e. it will not appear in bound.kwargs). This behavior I suspect is the intention of the docs saying "Contains only explicitly bound arguments." but still seems easily misused when .arguments is being used as a frontend for adding additional arguments. To me just brainstorming again it seems it'd be useful to provide a harder-to-misuse frontend, e.g. `BoundArguments.with_arguments(*args, **kwargs)` that returns a bound arguments with some additional to-be-bound arguments which may end up in `kwargs`. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41745> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
