Yeah, toml isn't great for that. It's greatly preferable to yaml for human-readable config. Json is better as a serialisation format. DSLs are bit vexed, not least because they're often horrible in themselves - cruft-accumulating hacks with no tooling, blurring the distinction between code and config often as a workaround for unwieldy dev processes. That's certainly not true of all DSLs, though (can't speak for Github Actions) and there is a need for a simple common base syntax/parser for them. I don't think yaml is a good solution. Being a cantankerous old git, I tend to think the problem of a common base syntax/parser for DSLs was solved 70 years ago: s-expressions/lisp.
