[issue32361] global / nonlocal interference : is this a bug, a feature or a design hole ?

New submission from Camion : Hello, "PEP 3104 -- Access to Names in Outer Scopes" introduced the keywords "global" and "nonlocal". but didn't make clear (to me) if this behaviour is a bug, an intentional feature, or a design hole which might be considered good or bad. I have observed that w

Christian Heimes added the comment: Let's see what's missing: * alpn_protocols -- OpenSSL doesn't have SSL_CTX_get_alpn_protos(), so we'd have to keep the list around ourselves. * npn_protocols -- deprecated, I'd rather add a getter * servername_callback -- simply expose the PyObject* from our
