Remarks

CopyTempIfNecessary will enforce the creation of a prvalue. This is UE's equivalent of the exposition std::decay-copy: https://eel.is/c++draft/expos.only.func It doesn't static assert like CopyTemp, because it is useful in templates or macros where it's not obvious what the argument is, but you want to create a PR value without stopping compilation.
