I read the documentation on Boost.PropertyTree support for JSON, and
came to the conclusion that I did not want to be constrained by the
limitations imposed by Boost.PropertyTree, etc.

Interesting, though, that it has to do with Boost.Spirit.Classic.

At the end of the day I decided to roll my own AST and Boost.Spirit.Qi
parser. So far so good, it's not that complicated.
