[issue15870] PyType_FromSpec should take metaclass as an argument

[Christian Tismer]

Christian Tismer <tismer at stackless.com> added the comment:

Since PyPy does not use the Limited API, PySide can quite easily work around the limitations by directly working with the type object. 

But the usage of PyType_Modified() would make very much sense for PySide‘s new switchable features. That would work immediately without any change, because we already use that function to invalidate Python 3.10‘s type cache.
