I’ve been working on a configuration format [1] that looks surprisingly similar to this!

That said, the expectation in CONL is that the entire structure is one document. A separate syntax for multiline comments also enables nice things like syntax highlighting the nested portions.

I do like the purity of just a = b, but it seems harder to provide good error messages with so much flexibility
