I will say that for me, `ArgSpec` makes me think of `inspect.getargspec()` and friends: https://docs.python.org/3/library/inspect.html#inspect.getargspec.

Hi Mark. ParamSpec sounds satisfactory for me; the name is short enough to type it without the code completion help :) Regarding explicit support for pos-only and kw-only parameters. I thought about things like @add_logging def f(a: int, /, b: str, c: float) -> None: ... @add_logging def g(a: int = 0) -> None: ... "f()" can be called as f(1, "abc", c=3.14) or f(1, b="abc", c=3.14); f(a=1, b="abc", c=3.14) is forbidden for example. "g()" allows g() and g(1). There are very many different call variants with interesting corner cases. I suspect that the proposed PEP ignores these differences, please correct me if I'm wrong.

I think a lot of people use argument and parameter interchangeably too, at least that's what I noticed.

Hi Andrew, My intention in the writing of this PEP was to require implementations to handle all of those cases. Our example implementation in Pyre does in fact preserve all of that information, and your example would work in the way you described. Is there some wording that you think we should add to the PEP in order to make this more explicit? Best, Mark Mendoza

Don’t have strong opinions on this and definitely don’t want the naming to block the PEP. I don’t think correctness when it comes to terminology for something as fundamental as a programming language is a bad thing. Given how prevalent Python is as a teaching tool in CS101 classes I think using the right words for things – even if the distinction is not as clear in Python – to me personally seems like something that’s worth prioritizing.

To me, ParamSpec is just longer (and slower to pronounce) for a reason that's debatable and smells like hyper-correctness. After all we typically write *args and **kwargs so the term "arguments" still comes up frequently when discussing function definitions. I used to believe in the rule that "parameters" are what's part of the function definition and "arguments" are used in a function call, but now I think that the distinction is just a distraction, and trying to follow it a lost cause and probably a form of hyper-correctness.
