[Python-ideas] Dict joining using + and +=

[Karthikeyan]

Just to add to the discussion this was brought up previously as part of PEP
448 unpacking generalizations that also added {**x, **y} to merge two dicts
in Python 3.5.

Previous python ideas thread :
https://mail.python.org/pipermail/python-ideas/2015-February/031748.html
LWN summary : https://lwn.net/Articles/635397/

The previous thread is worth reading as some of the points still stand even
with {**x, **y} added.
