Even if they get a little stale, that's not entirely a bad thing as little things like that are an easy contribution for people new to Nim. That fix they make is the initial seed of volunteering and becoming an active community member.
Anyhow, maybe Nim by Example as a starting point and it can find a better home if that's not the right place later? Anyone interested in WASM and Nim want to try a hand at a PR?
