that's a really good idea.  you have access to the repo.
https://git.libre-riscv.org/?p=crowdsupply.git;a=summary

good responses, good justifications for what you did (on previous comment),
use the answers you gave to create comments.

in particular make sure that the recursive case is commented, as it wasn't
clear that the function *is* used recursively! (no comments to that effect,
i didn't notice).

the singleton thing is so unsafe, it causes so many problems and wastes
so much time trying to track it down, it's just not worth the hassle of
trying to save 1 lines of code.  please use the pattern that i provided
instead.
