In the book Borland C++ 4.5 Object-Oriented Programming by Ted Faison, Sam's Publishing, page
603, there is an example using the Borland template class library. First, the idea is to instantiate
a class of type TListImp(from a template) and then instantiate an object of that type. And then to
instantiate a class of type TListIteratorImp from a template, and then to instantiate an object of
that type. The TListIterator object will be used to move through the TListImp object. The details
about these class templates are not what my question is about, but rather the syntax of one of the
lines in the program is:
     TListIteratorImp<string>     next(a);  // where a is an object of type TListImp<string>
     ...
     while(next)     // ??
     ...
     What does this line mean? How does it work?
