Detailed Description

template<typename ConcreteType, template< typename T > class... Traits>
class mlir::Op< ConcreteType, Traits >

This provides public APIs that all operations should have.

The template argument 'ConcreteType' should be the concrete type by CRTP and the others are base classes by the policy pattern.
