I think they meant tools like docker or npm and stuff. Not calling people tools.

heh, I didn't even consider this interpretation of the above; sorry about that. I meant "tools like Docker keep using it", not people. But I still don't know what you're talking about; YAML has an 83 page spec that includes pointers, and uses tons of random confusing symbols. I say "maybe it's just me" in some of these posts, but I know it's not: I've watched many of my coworkers get it wrong the first time for years and then have to be corrected. A quick common example I see in CI config all the time: If I write version: 1.10, that's a number, then I decide to move to latest so I write version: 1.10.x, that's a string. Oops, we were never using version "1.10" we were using "1.1". Everything about it is implicit and bad. Now, it's easy to say "always use quoted strings", and I agree, but then why the hell does it have bare strings in the first place? That seems like an easy enough oversight or typo to make, and it will be made.
