That’s some hard-core reading material right there… thanks, I’ll give it a go.
I am wondering how much of this stuff is implementable on top of elm/parser. If that does not expose the features needed, I’ll most likely just stick with what I can do with extending elm/parser as I don’t really want to re-design the parser from scratch.
Also noting that elm/parser is a kernel package - not sure if it really needs to be, or that is just for some speed ups? But it means I can’t just clone elm/parser and make small modifications.
