I suggest porting the parser to Spirit2. It is so much faster and
flexible. Attribute handling of recursive types is built-in. Your
grammars will be a lot better and simpler.

I'll be accepting a set of (peer reviewed) reusable grammars as
part of Spirit2 distrib. I'd be interested in having a JSON
grammar. OvermindDL1's grammar is a good candidate. It would be
super if you both can iron out the details.
