People told me writing was too concise even before tablets. :) The _compiler_ was written in pseudo code by humans. It generated real code for the target machine so some serious porting was required for a new architecture. F40 was amazingly aggressive, actually. It used all 16 registers before resorting to temp variables and did common subexpression reduction within individual statements. Not always correctly, unfortunately.
