[issue20326] Argument Clinic should use a non-error-prone syntax to mark text signatures

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

What if the __text_signature__ and __doc__ getter will call ast.parse() (actually compile()) on signature candidate? If it fails, then builtin has no signature, the __text_signature__ getter returns '', and the __doc__ getter returns all original docstring.
