Polymorphic copyable function wrapper.
The std::copyable_function class template is a call wrapper similar to std::function, but it does not provide information about it's target, and preserves constness.
It also supports const-qualification, ref-qualification, and no-throw guarantees. The qualifications and exception-specification of the copyable_function::operator() member function are respected when invoking the target function.
