Ah, great. This used to be rather clunky to do.

  Really? This is how that was done in Python 2.7 and it doesn't seem that much clunkier to me... dict(dict1, **dict2)

    That's only allowed if the keys in the second dictionary are valid Python identifiers (don't contain spaces etc.). I think CPython is OK with this, but PyPy is not.

    Interesting. I never thought of that. I also asked a question about this on StackOver flow once and no one suggested that. Very useful.

    It has a lot of issues. The biggest one for me is the following: Dicts are intended to take hashable keys (e.g. frozensets or tuples), but this method fails in Python 3 when keys are not strings.
