1. You can search on any type that is comparable to the key_type, rather than just the key_type. (The STL associative containers only allows searches on the same type as the key.)

BTW, there is also an extention in STLPort which supports comparisons like this. I often wondered why this isn't supported by the standard containers. Any idea? S.
