I had the impression that C++ strings arent implemented as a template class, so they dont come under the standard template library.
A little googling appears to confirm this.

However, I've also seen references to "STL strings", which apparently refer to C++ strings, i.e. those using <string>
Are C++ strings considered as part of the STL then?
