Hi,

There is a thread on comp.lang.c++.moderated where the problem of 
manipulating with "heavy" data in STL containers was raised.
The name of the thread is "Messign with expensive objects in containers".

I have posted a solution with the help of a simple view adaptor class 
that I wrote a while ago. The code with examples and documentation is here:

Alberto Barbati suggested to post it here for review.
It is different from boost::multi_index in that view operates on already 
existing objects or sequences.

Note: the view class itself is very simple and as a concept is only a 
fraction of what is available in the View Template Library:

I would like to know your opinion about the view as a concept, and its 
simple implementation that I referenced above. It might fit into the 
Containers category of Boost libraries.

Regards,
