I am waiting 3.7 compatibility for dict insertion order which I rely in my last project. I know I could use workarounds but now it is safe and stable and I am not in a hurry. Until then waiting in CPython.
> Changed in version 3.7: Dictionary order is guaranteed to be insertion order. This behavior was an implementation detail of CPython from 3.6. [0]
