[section:is_scalar is_scalar]
   template <class T>
   struct is_scalar : public __tof {};
  
__inherit If T is a (possibly cv-qualified) scalar type then inherits from 
__true_type, otherwise inherits from __false_type.  Scalar types include
integral, floating point, enumeration, pointer, and pointer-to-member types.

__std_ref 3.9p10.

__header ` #include <boost/type_traits/is_scalar.hpp>` or ` #include <boost/type_traits.hpp>`

__compat If the compiler does not support partial-specialization of class templates, 
then this template can not be used with function types.

__examples

[:`is_scalar<int*>` inherits from `__true_type`.]

[:`is_scalar<int>::type` is the type `__true_type`.]

[:`is_scalar<double>::value` is an integral constant 
expression that evaluates to /true/.]

[:`is_scalar<int (*)(long)>::value` is an integral constant 
expression that evaluates to /true/.]

[:`is_scalar<int (MyClass::*)(long)>::value` is an integral constant 
expression that evaluates to /true/.]

[:`is_scalar<int (MyClass::*)>::value` is an integral constant 
expression that evaluates to /true/.]

[:`is_scalar<T>::value_type` is the type `bool`.]
