This looks amazing. Took me some time to find the author (https://fabiomaia.eu). Will drop a message to ask if it'd be possible to have a similar tool for Python. I find it useful to teach new engineers how to find the source code in the cpython repository, check if the code is Python or C, and understand what the code does (some times the docs are a bit lacking/confusing for newcomers).

Why not create your own? This is as wild as open-source expectations of a speedy implementation, addressing issues quickly, etc. Folks always want more and more.
