Very minor bug in Pythonista 3.4

[upwart]

When I run this code

import inspect

class X:
    ...

sig = inspect.signature(X)

on Pythonista 3.4, a
ValueError : No signature for builtin <class 'object'>
exception is raised.

This did not happen on Pythonista 3.3 and not on a Windows machine running Python 3.10.4 (same version as Pythonista 3.4).
If I add an __init__ method, the exception is not raised anymore,

Of course, I can just use a try/except block to solve the problem, but it is very strange.

@upwart known problem (not of Pythonista it-self), see here
