Another obvious way to do it, but I'm +1 on it.
A small side point however - PEP 584 reads:
> To create a new dict containing the merged items of two (or more) dicts, one

> {**d1, **d2}
> but this is neither obvious nor easily discoverable. It is only guaranteed to

The references cited does not back this assertion up. Perhaps the intent is to
reference the "cool/weird hack" dict(d1, **d2) (see
https://mail.python.org/pipermail/python-dev/2010-April/099485.html and
https://mail.python.org/pipermail/python-dev/2010-April/099459.html), which
allowed any hashable keys in Python 2 but only strings in Python 3.
If I see {**d1, **d2}, my expectations are that this is the new generalized
unpacking and I currently expect any keys to be allowed, and the PEP should be
updated to accurately reflect this to prevent future misunderstandings.
