Research direction
Start with the linked Lib/re/init.py location and review the existing re documentation around Scanner. Add a concise description of what re.Scanner does and consider the proposed example docstring. Done means the standard-library documentation explains the feature clearly and reflects its practical use.
Written by the indexing model from the issue text.
Description
Documentation
re.Scanner is currently marked as "experimental" but was added to the standard library 24 years ago[0].
People seem to think this is an interesting feature[1][2] and a github code search for re.Scanner( gives >500 hits[3],
suggesting people have found practical uses for the class.
Proposal
I suggest we add a few lines to the docs describing what it is and perhaps a short docstring with an example.
