Good luck getting a high performance implementation of A=B+C without memory allocation out of a library.

rolling your own is pretty easy, it is a shame that the C++ standard library is a dire wasteland of bad implementations. you are right that valarray will do heap allocations and making it work on the stack is a real ballache.

This is really not hard using expression templates.
