[New-bugs-announce] [issue18254] Accessing attr dict at definition time of a class from a metaclass results in changed type.

[Archard Lias]

New submission from Archard Lias:

Accessing (just iterating or accessing in any way) the dict_proxy to the attribute dictionary in the `MessageMeta` metaclass, results in a change of "type" in any metaclass inheriting class definitions.

Reproducible in CPython versions (tested so far):
3.2.2
3.2.3

Works as of, or at least behaves as I subjectively intended to use it (only version tested)
3.3.2
