That's why I wondered if it could be reasonably included (without  
introducing a ton of new stuff to the language).

so it should be usable like x.dotProduct(y), right?
sounds fine for me.

Unfortunately I can't even try to implement it cause my Core 2 is slightly  
too old ;)
Was introduced with Penryn architecture.
