Are you still planning to do this? I've made a few changes to parsing of JSON literals that makes implementing this change much easier, and also simplifies getting full coverage.

If #989 is done, this could be supported. E.g.: ```c++ enum class E { e1, e2, e3 }; struct E_String { // is_string_like E e; E_String(E); explicit E_String(string_view); operator string_view()...

Do any associative containers have that? I've checked Unordered, and it's do not.

`boost::unordered_flat_map` has `rehash` which apprarently can do the equivalent of `shrink_to_fit` and more. Maybe we should explore this.

The initial problem was related to standlaone build, which is now not supported.

The order is now documented (as of release 1.81).

This has been done and released in 1.81

`value_to` converts maps to objects when the key is `is_string_like`. If not, it is converted to array. If your key type is not `is_string_like`, but you can "stringize" it and...
