Again, you are wrong to generalize.  It depends on the situation, the 
abstraction in question, and the code.

And you were completely wrong when you said that.  Perhaps in /your/ 
field of programming you are correct - but you are ignoring the rest of 
the world.

Often that is correct.  Often it is /not/ correct.  The only thing we 
can all be sure of is that your laughable attempt at a benchmark here 
bears no relation to the real world - especially not the real world of 
small-systems programming.

For every one of your favourite big x86 chips sold, there will be a 
hundred small microcontrollers - none of which has branch prediction.
