"My text editor, KeenWrite, allows users to reference YAML variables as paths while editing documents." Another thing that would help in these template languages is if they'd pervasively track the sources of things, and let you view the final output of the templating process with some mechanism for viewing those annotations. Then when you look at the final result of some templating operation and can't figure out why "AWS_ENV_VAR" is "lol don't deploy this", you have some chance of figuring out where it came from. This is yet another entry in the class of things that aren't too hard to add from the beginning, but good luck retrofitting it on after the fact.
