Re: [boost] [review][JSON] json::value as a vocabulary type

My understanding of a "vocabulary type" is that it should be usable (not necessarily with maximum efficiency) for *any* usage. In the case of JSON that would mean that I should be able to represent any value that corresponds to a valid JSON when converted to text. I do not think that json::value can claim that without the ability to serialize arbitrarily big numbers.

I fully agree with this statement. json::value *needs* to support arbitrary numbers. It's incomplete without it. Maybe the author of multiprecision can advise on the best type to use there (gmp or mpfr?).
