[New-bugs-announce] [issue26729] Incorrect __text_signature__ for sorted

[Erik Welch]

New submission from Erik Welch:

The first argument to sorted is positional-only, so the text signature should be:

sorted($module, iterable, /, key=None, reverse=False)

instead of

sorted($module, iterable, key=None, reverse=False)

To reproduce the issue, attempt to use "iterable" as a keyword argument:

>>> import inspect
>>> sig = inspect.signature(sorted)
>>> sig.bind(iterable=[])  # should raise, but doesn't
>>> sorted(iterable=[])  # raises TypeError
