Dennis Bingaman,
        A handcrafted struct or class can beat a tuple in all categories
except one: time to define it. A tuple shines as a way to return multiple
values from a function without haven't to result to creating a struct/class
or worse changing the signature of the function/method by having them, the
return values, passed in as reference(s) or pointer(s) parameters. The
latter would obscure the innate documentation on how a function is to be
used. i.e. Is this parameter and in, in/out, or out parameter? Add onto all
of this all the methods and operators that get generated for you and the
tuple's ease of use become apparent.

Subject: [boost] boost::tuples

I have been using the STL for some time now and have been investigating 
possible use of the boost libraries in future projects.  The most useful 
library I have found so far was the boost::lamda library.  I was reading 
the documentation and experimenting around with the boost::tuples library. 
 The documentation is excellent and very complete and now I understand how 
to create tuples and maybe use them is some limited way.  Thing is, I 
can't seem to grasp what advantages there are of tuples over structures 
and classes?  Can someone tell me; what are the benefits of tuples over 
structures or classes?

Thanks,
Dennis Bingaman
