Théo DELRIEU 45c8af2c46 add new is_constructible_* traits used in from_json ... is_compatible_* traits were used in from_json, but it made no sense whatsoever. It used to work because of non-SFINAE correctness + json_ref unconstrained variadic template constructor. SFINAE checks are becoming quite complex, we need a specification of some sort describing: * which concepts the library uses * how the conversion to/from json works in detail Having such a specification would really help simplifying the current code (as well as having meaningful checks).
