[Python-Dev] Non-string keys in type dict (original) (raw)

During the Language Summit 2011 (*), it was discussed that PyPy and Jython don't support non-string key in type dict. An issue was open to emit a warning on such dict, but the patch has not been commited yet.

It's the issue #11455. As written in the issue, there are two ways to create such type:

class A(object): locals()[42] = "abc"

or

type("A", (object,), {42: "abc"})

Both look like an ugly hack.
