If what you want is a parser not a reader, I reworked this [1] recently
and to the limits of my testing it's "correct" in that it parses every
reader construct I thought of to throw at it. You could improve it, I
believe that #() nesting is supported by this grammar, but I was trying
not to complicate evaluation semantics with the parser grammar too much.
Debugging ANTLR grammars is not what I'd call friendly.
A "useful" subset of this grammar with nicer evaluation semantics is
used, a reader implemented and tested here [2]

I'm thoroughly confused. If I want to parse clojure code from string
without evaluating or caring a lot about its context, I'm out of luck.
EDN tools choke on reader macros ( #(blah % blah) is not valid EDN
), yet more context-aware tools like read-string with *read-eval*
set to false choke on namespace-specific tokens like ::om/pass.
What would be a best choice to parse Clojure code into analyzable
data structure while both parsing all of it (so, not just
clojure.edn/read), _and_ not going the entire
namespaces/shadowing/etc dance?
