Sounds good to me, and I like the name "Jaxon", which currently seems
to be mostly used as a spelling variant of "Jackson".

If you are going to break JavaScript compatibility, which is one of
JSON's important features, then you might as well go a little further:

* The full range of IEEE 754 floats

* Language tagging in data

* XSD simple types

I'd add 0.inf, -0.inf, and 0.nan syntax for infinities and NaNs, ISO
8601 syntax for gDate and gDateTime, and the ability to add XSD simple
type names (prepended with "^^") and language tags (prepended with "@")
to a JSON literal in either order.  N3 allows this on string literals
only, but 32^^integer seems better to me than "32"^^integer.

It would probably make sense to allow only a subset of simple types.
