executor_binder::executor_binder (5 of 9 overloads)

Construct a copy of a different executor wrapper type, but specify a different executor.

template<
    typename U,
    typename OtherExecutor>
executor_binder(
    executor_arg_t ,
    const executor_type & e,
    const executor_binder< U, OtherExecutor > & other,
    constraint_t< is_constructible< T, U >::value >  = 0);

This constructor is only valid if the type T is constructible from type U.
