concept bool Copyable =

 (ranges TS)

The concept Copyable<T> specifies that T is an Movable object type that can also copied (that is, it supports copy construction and copy assignment).

Notes

It is intended that Copyable<T> also requires Assignable<T&, const T> (assignment from const rvalue) and Assignable<T&, T&> (assignment from non-const lvalue) to be satisfied.

specifies that an object of a type can be moved and swapped
