Remarks

Assume elements are compatible with themselves - avoids problems with generated copy constructors of arrays of forwarded types, e.g.:

struct FThing;

struct FOuter { TArray Arr; // this will cause errors without this workaround };

This should be changed to use std::disjunction and std::is_constructible, and the usage changed to use ::value instead of Value, when std::disjunction (C++17) is available everywhere.
