When using a custom classdict to implement a DSL or use in the body of a class definition, from what I can tell by experiment, the classdict takes priority, and the surrounding context is only referenced if trying to get an item from the classdict raises `KeyError`.
There is at least one case in which I would like to do the reverse, and have the classdict be secondary to (masked by) any variables defined in the context surrounding the execution of the class body. I have been able to at least unmask builtins by having the classdict object first try to get a result from `__builtins__` and then fall back to itself. Also, in the actual class body, declaring a variable as `global` seems to be a workaround for global variables, but that has to be done explicitly in the body of any subclass that needs it. Also, that does not handle non-globals in its surrounding context. I'm not sure what the best way to deal with this would be, but my first thought is to maybe have a property that can be set on the metaclass type such as `metacls.relictant_classdict = True`. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/4YLADJ7BCUI5KZCZLIHHZJXGWAAX5YY6/ Code of Conduct: http://python.org/psf/codeofconduct/
