…h default value. `concept IsField = std::is_base_of_v<Field, T>`
Replaced template specializations with a single `if constexpr` block.

A couple of little things to tidy up, otherwise looks great!

@tomc271 Is there a reason we can't do:
Suggested change
| requires IsField<T>&& IsField<U>&& IsField<V> | |
| template <IsField T, IsField U, IsField V, | |
| typename ResultType = std::common_type_t<T, U, V>> |
Is it because T etc in this case are concepts, and common_type_t takes templates?

Could you run clang-tidy/clang-format over this? We should always have braces with if, and not have else following return
