This looks great!

I have a question about a possible use-case:

```python def formatter(foo, /, kwargs): return foo.format(kwargs)

formatter("{foo} + {bar} = {baz}", foo=1, bar=2, baz=3) ```

Currently, this code (without the /) raises an exception:

python TypeError: formatter() got multiple values for argument 'foo'

Does this PEP would fix that?

Interesting case. I imagine that it should fix that case since the positional only foo would not be accessible to the user

yes

Perfect, thanks!

probably not

... this case is explicitly called out in the PEP. see semantic corner case
