AFAIK, Junior doesn't use any of the STL features, and is written very 
carefully to avoid anything in C++ that will produce inefficient code.  
People who write C++ usually don't want to restrain themselves like
that.

FWIW, Groff, the GNU replacement fro the Troff/Nroff package, is also 
written in C++, and it also carefully avoids any expensive C++ features.

You can't even dereference a pointer in C++ without being sure it wasn't 
overloaded by some class that is called deep inside the libraries you are 
using.
