New submission from Alex Hayes: I imagine that this is by design (likely because it can't be implemented) however I wanted to check if this was the case.
Instances of types.MappingProxyType can't be pickled. For example; ``` import pickle from types import MappingProxyType eggs = MappingProxyType(dict(sausage=True)) pickle.dumps(eggs) ``` Raises: TypeError: can't pickle mappingproxy objects ---- Is this the desired behaviour or is it a bug? ---------- components: Library (Lib) messages: 300284 nosy: Alex Hayes priority: normal severity: normal status: open title: MappingProxyType can not be pickled type: behavior versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31209> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
