You took the works right out of my mouth!  I think that once we start  
thinking about Pd as a language in itself, then people will start to  
think how to optimize it as well.  There is no doubt in my mind that C  
code would be faster than Pd for most things, but, like Java, Ruby,  
SmallTalk, there is something to be gained by using it to program.   
Assembly is even faster than C, so why aren't people writing objects in  
  assembly?
