87,function to get the size of a array,flier,mark_rodgers,"{{{
why not add a function which can get the size of a 
array? just like this

#include <boost/type_traits.hpp>

template <bool IS_CLASS>
struct SizeOfArrayHelper;

template <>
struct SizeOfArrayHelper<false>
{
  template<typename T>
  static inline int SizeOfArray(const T& array)
  {
    BOOST_STATIC_ASSERT(boost::is_array<T>::value);

    return sizeof(array) / sizeof(array[0]);
  }

  static inline int SizeOfArray(char *str)
  {
    return strlen(str);
  }

  static inline int SizeOfArray(const char *str)
  {
    return strlen(str);
  }
};

template <>
struct SizeOfArrayHelper<true>
{
  template<typename T>
  static inline int SizeOfArray(const T& array)
  {
    BOOST_STATIC_ASSERT(boost::is_class<T>::value);

    return array.size();
  }
};

template <typename T>
inline int SizeOfArray(const T& array)
{
  return 
SizeOfArrayHelper<boost::is_class<T>::value>::SizeOfArr
ay(array);
}
