Indeed. For the purpose of this optimization, a string algorithm could be used ;)
Also, I guess for those that are interested in optimizing such expressions, 
there should be another way IMO.

Allow making two or more containers of *the same type*, seem like a continuous 
range.
We could then have something similar to:

s = concatenate( a, b, c);

This will also be much more general, allowing to copy two deques into a range, 
or something similar.

But more on that, when we (Matt Wilson and me) will present the first version of 
rtl (Ranges Template Library) ;)

Best,
John
