Hi Terje, This is how the parsing works in Cursive. I have a classical lexer/parser split because IntelliJ forces me to do that. That said, I like it that way, and I believe it makes things more flexible. I've been able to make a couple of special-case parsers easily on top of the lexer - I'm about to start work on another one for Parinfer support.
I can't speak to why the Clojure reader works the way it does, but what you suggest is definitely possible and works well.
