template< class T >
struct is_execution_policy;
(parallelism TS)

Checks whether T is a standard or implementation-defined execution policy type.

Provides the member constant value which is equal to true, if T is execution_policy, sequential_execution_policy, parallel_execution_policy, parallel_vector_execution_policy, or an implementation-defined execution policy type. Otherwise, value is equal to false.

The behavior of a program that adds specializations for is_execution_policy is undefined.
