[lib] forking toml?

I have YAML on the roadmap for my Orsetto hobby project, and I suppose I should add TOML too. I’ll be watching this thread to get a feel for which is likely to be the higher community priority. My own preference is for YAML first, then TOML later, but I’m open to reconsidering if there are significant problems with YAML that I don’t know about because I generally try to avoid human-readable configuration files altogether in my designs.
