Feature request: produce (or deconstruct)

It would be a useful extension to be able to produce maps with keys cased in one specific flavour.

One example use would be to produce Javascript-style camelCase API responses while maintaining structs and maps internally in snake_case.

If this sounds like a reasonable extension to the maintainers I'd prepare a PR.

Hm, I could see this being pretty useful. I'd probably include it as an extra module, rather than having it brought in by the __using__ macro by default, but this sounds like a good feature.
