This is important in a wider context.  For example, in the project to add machine-readable output to core utilities, we'd like to be able to parse these into the same machine-readable format.  Apple has the CoreFoundation library for this, which provides a load of stuff, but most importantly number, string, date, dictionary, and array types (i.e. the sorts of things that you'd want in JSON-like serialisation formats).

The simplest way of implementing this would be to just provide some C wrappers around the libc++ implementations, but that might not be ideal...
