I guess.  If you're willing to have your compiler "optimize" external  
function calls.  There was a discussion on that sort of thing here  
before, comparing C to languages with defined "built-in" "functions."   
I don't remember whether there was any consensus.   Sure, you could  
build a special-purpose arduino-language compiler, but that would make  
the package less attractive from other perspectives...

Besides, we're talking about the difference between a ~2.6MHz and  
~120kHz pin toggle rate here; even most of the people who think they  
need the functions to be faster are wrong, and I suspect that it's  
just as well that it's slower, given the rats nest of long wires that  
frequently end up being used to connect the arduino to external  
devices...
