This is true and would be useful, but I think I can see a problem (which
might very well be the reason why it isn't something people already do):
after a while, there will be literally thousands of discarded stuff. How am
I supposed to search and find the alternative that works, especially if I
am now working on a different problem than 6 months ago when the stuff was
originally written? Is this search faster than starting from scratch? IMHO
the answer is that what needs to be saved is a higher-level description,
not a complete brain dump of the process.
There is also a difference between what is interesting for teaching people
(beginners) and what is interesting for future reference for the team that
develops the code. These categories need different levels of detail,
different kind of information.
