Well, the not-so-sound logic of: I was trying to figure out why 100 unit-tests were failing, I spotted this one bit, commented it out and - since everything(?) was working like before again - decided to figure out why...
What you mention regarding the commit log, that's exactly what I've been looking into... Basically, I'm 99% convinced it's this one: <https://github.com/nim-lang/Nim/commit/d259099ef043e68c2a1f44d01889237af2a8880d> The problem is it affects bits that have been written too long ago and I find myself trying to figure out why we did things in the way we did back then (without really remembering the answer lol).
