Bug report

turtle.teleport added in#103974 seems not quite correct.

Why?

1. It is produced automagically fromTurtle.teleport instance method. It has this signature:def teleport(self, x=None, y=None, *, fill_gap: bool = False) -> None:
2. The result functionturtle.teleport has this signature:def teleport(x, y=None, fill_gap=None)

Notice that it is missingx=None default and for some reasonfill_gap is not a kw-only anymore.

The second problem happens because inside it usesinspect.getargs:

So, when I try to runturtle.teleport I get:

Traceback (mostrecentcalllast):File"/Users/sobolev/Desktop/cpython/ex.py",line60,in<module>print(teleport())^^^^^^^^^^TypeError:teleport()missing1requiredpositionalargument:'x'

And with just one arg:

Traceback (mostrecentcalllast):File"/Users/sobolev/Desktop/cpython/ex.py",line60,in<module>print(teleport(1))^^^^^^^^^^^File"<string>",line4,inteleportTypeError:Turtle.teleport()takesfrom1to3positionalargumentsbut4weregiven

Annotations are also missing. It is not a big problem, but it is inconvenient.

I propose usinginspect.signature instead. It will allow us using pos-only and keyword-only params with ease.

I have a PR ready.
