Wouldn't have been difficult to sleuth using my profile here, but Nim-lang. Specifically because it's basically an all-in-one, being easy and fast+capable+flexible. Maybe not enough to go by (and I didn't finish/release it), but some code that I actually wrote (+what it's loading)

For further context on the statement by the creator, it was complaining about the "grammar" of singular they. Aside from that being an obvious culture-war BS dogwhistle, the person who quit knew them closely so I don't think it was an overreaction or misunderstanding.
