Would it be possible to augment the enable_if_constructors.cpp test 
with a templated container?  Maybe something like:

template <class charT>
struct string
{
   template <class It>
   string(It begin, It end, typename 
enable_if<!is_arithmetic<It>::value>::type* = 0)
     : data(end-begin) {}

   int data;
};

#include <assert.h>

int main (int ,char *[])
{
        char sa[] = "123456";
        assert(string<char>(sa, sa+6).data == 6);
}

Thanks,
