New issue 3109: Inheriting from a function produces nonsensical-ish error message https://bitbucket.org/pypy/pypy/issues/3109/inheriting-from-a-function-produces
Julian Berman: ``` >>> def foo(): ... pass >>> >>> class Bar(foo): ... pass Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'internal-code' object expected, got 'str' instead 'internal-code' object expected, got 'str' instead ``` \(CPython is no better, FWIW, on 3.7: ``` >>> def foo(): ... pass ... >>> >>> class Bar(foo): ... pass ... Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function() argument 1 must be code, not str ``` \) Something like “superclasses of a class must be instances of `type` \(i.e. classes\)” would be a lot nicer \(if in fact that is the criteria, I forget\) _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
