Plus the 64-bit integer problem, really 52-bit integers, due to JS not having integers.

JSON itself is not limited to neither 52 nor 64-bit integers.

    integer = -? (digit | onenine digit+)

Most good parsers have an option to parse to integers or arbitrary precision decimals.

[VMG]

Agreed. Which means that Javascript does not have a good parser.
