 // elem: loop variable

 // iter_t: iterator type
 // iter: prefix for begin() and end()
 //
 // contains a hack for Microsoft Visual C++ 5.0, because code like
 //
 //   for(int i=0; i<10; ++i) { ... do something ... }
 //   for(int i=0; i<10; ++i) { ... do something again ... }
 //
 // is illegal with Microsoft Extensions enabled, but without Microsoft
 // Extensions, the Microsoft STL does not work :-(.
 // So we code the line number (__LINE__) into our loop variables.
