This is a modest proposal to consider having sorted containers (http://www.grantjenks.com/docs/sortedcontainers/) in standard library.
+1 from me, but if and only if Grant Jenks (its author) wants that too.
It's first-rate code in all respects, including that it's a fine example _of_ Python programming (it's not written in C - in Python).
People often say "well, put a thing on PyPI first, and see whether people really want it!".
SortedContainers has been on PyPI for years straight now, and still gets hundreds of thousands of downloads from there every day:
https://pypistats.org/packages/sortedcontainers
So it's already widely adopted in the community. What else would it need to prove?
If it still doesn't qualify, "well, put a thing on PyPI first" is just obstructionism ;-)
