Make the spec concrete already

Currently this specification is casual, as we gather feedback from implementors. A more rigorous e.g. BNF will follow.

Perhaps it's time to just write the BNF? Please?

It makes it much harder to advocate for the use of EDN without this sort of thing, especially if we're not a Clojure shop.

Ping on that.

I’m contributing to the most complete EDN parser in Python that I know of (edn_format) but the spec is too vague and clojure.edn/read-string accepts a lot more than what’s defined here. It’s really hard to properly implement a parser with no formal spec.

We can’t seriously use EDN outside of the Clojure world without a proper grammar.

This issue is a duplicate of the #56

@avodonosov Not really. This is about giving them a kick up the arse.

Hi. I am currently making an ANTLR grammar for this. Maybe it will be as good as having a BNF
