[issue30744] Local variable assignment is broken when combined with threads + tracing + closures

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

No, as locals() never returns the write-through proxy in the latest version of the PEP - it only ever returns the dynamic snapshot namespace (retrieving it from the proxy if necessary).

To get access to the write-through proxy in Python level code, you have to access frame.f_locals directly (which trace functions will do by necessity, since that's the only way they have to get at the function locals).
