No, fastcat does not exist.  I'm suggesting that it may be easier for
Chateauneu to create an optimized method (fastcat or such) that accepts
multiple operands rather than wrestling with operators that accept only two
operands.

Jim,
    I don't show a fatcat method in my stl. I am on Windows XP with VS 2003.
    is this part of the standard string or boost library?

I know next to nothing about C++, STL, so forgive my ignorance.  But,
couldn't this performance problem be solved by calling a method that
concatenates multiple std::strings?  E.g. 

a.fastcat(b, c, d, e);  // returns &a

Maybe this is naive, but does every problem require an operator?

If you want to see it, let me know.

    

Yes, thanks ! If you wish, I can send mine (330 lines, 11 k-bytes).

Could we take the best of both, and maybe put it in the string algo lib ?
