Good point. Although it seems that some of the non-human-friendly features 
of PICs (like banked memory) were not absolutely necessary, even though I'm 
sure the designers knew that these low-end microcontrollers would be 
programmed in assembly, without the benefit of a compiler to hide the 
ugliness.
