Python keyword args can be any string

[Steven D'Aprano]

Today I learned that **kwargs style keyword arguments can be any string:


py> def test(**kw):
...     print(kw)
... 
py> kwargs = {'abc-def': 42, '': 23, '---': 999, '123': 17}
py> test(**kwargs)
{'': 23, '123': 17, '---': 999, 'abc-def': 42}


Bug or feature?
