I agree about the distinction you made from the human perspective and you put it well.

I have always hated YAML, and still to this day, because I cannot write a yaml file, the indentation makes no sense to me and the list syntax is black magic (you actually have several ways to write those, once again the indentation implication is obscure). So while agreeing on the goal to be written/edited by humans to my perspective it fails at it.

Also 1e2 might not be the best example as this is just 100, but as someone who had to pass a lot of neural network training hyper-parameters : passing 1e-3 and so on is definitely a use-case. I am on the negative values Xe-XX (and YAML 1.1 would parsed it OK) but I guess other domains could also use the positive side to pass values (maybe as upper limits like 1e5 or so).

I think the YAML format should have parsed those number formats from the beginning. If this is fixed now, good job, hopefully the default yaml parsers are going to be "fixed". I would still use TOML over YAML any day, waiting for a human-json (some already exist) to be popularized one day.
