[issue45302] 10 built-in functions need non-None .__text_signature__

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

There are reasons for this. There is no supported by inspect.signature() syntax to adequately define the signature of say getattr(). It has one required parameter and one optional parameter, but the default value of the optional parameter cannot be expressed.
