Detailed Description

A class to be use C++ objects in ArkScript.

A pointer to the value you want to store must be sent, thus the value must not be destroyed while the UserType lives, otherwise it would result in an UB when trying to use the object

MyType object;
UserType a(&object);
if (a.is<MyType>())
