Conditional copy and promote a type's scalar type to a PromotedType.

PromotedType	type to promote the scalar to.
CopyType	type of copy to perform.
Args	variadic arguments.

Parameters

args	variadic arguments to conditionally copy and promote.

Returns

a tuple where each element is either a reference to the original argument or a promoted copy of the argument.
