Type Trait Functions


bool __is_scalar( typename T )

Returns true if and only if T is a scalar type.

Scalar type is defined in Section 3.9 p10 of the Working Draft.


__is_arithmetic( T ) || __is_enumeration(T) ||

__is_pointer(T) || __is_member_pointer(T)

Scalar types have a built in meaning for operator < as well as operator ==. Therefore, __closure is not a scalar type.
