But Gennadiy is talking about code size, not execution speed. The very
fact that makes Fusion so fast, its ability to compile down to code that
looks like it was specifically written for the case at hand, means that
every usage will have almost exactly the same code, but slightly
different - as if it was written specifically for each case by hand.
