int i {0};
decltype (constfwd (i)) == int const &;
Forward value as const.
Belongs to the group of functions used to modify function argument cv and reference qualification.
Not a container function.
Should be applied with caution, as it may produce a dangling reference. In particular, the rule for extending the lifetime of a prvalue bound to a reference does not apply through a function call.
