...
Why would you cast twice when you can just call intValue instead ? Plus it is going to unbox to long, cast to int, and rebox to Integer, which does not seem very useful. I don't see the point on top of my head, do you have a good reason fo...

std::forward has a single use case: to cast a templated function parameter (inside the function) to the value category (lvalue or rvalue) the caller used to pass it. This allows rvalue arguments to be passed on as rvalues, and lvalues to be passed on as lvalues, a...
