Github PR #23204:
For a given element in a heap, we can leverage the fact that we can
search this element quicker thinking of the property of a heap. Therefore
out of h.index(x) that a list linear search uses, I propose to use a special written index method to look for an index of a heap element.This issue has been proposed on Github (with my changes to heapq also put there). Open a discussion under suggestion of Karthikeyan Singaravelan (tirkarthi).
