... wait, what?

I use the sort function of a standard library because it has been written by seasoned devs, reviewed, rewritten; use known algorithms and practices; and being part of a well known standard library it has a chance of still being maintained, distributed and available ten years from now on.

I don't know how you can even remotely compare that to an unmaintained code dump that someone made as a learning experiment over the week.

I'm not dissing on theses kinds of code release, they are great to learn from, but I would find it a bit foolish to base your whole product on it.
