            A metafunction returning the result type of any.
          
template< typename Sequence, typename F > struct any { typedef bool type; };
Table 1.59. Parameters
| Parameter | Requirement | Description | 
|---|---|---|
| 
                       | A model of Forward Sequence | Operation's argument | 
| 
                       | A model of unary Polymorphic Function Object | Operation's argument | 
result_of::any<Sequence, F>::type
            Return type: bool.
          
            Semantics: Returns the return type of
            any
            given a sequence of type Sequence
            and a unary Polymorphic
            Function Object of type F.
            The return type is always bool.
          
Constant.
