  1. Make sure the code is correct.


  2. Make sure the code is compact.


  3. If you want to use existing libraries, make sure you obey the same
        calling convention and data layout rules.


  4. If the micro controller has some special features, such as loop
        constructs, be sure that you can map source code to these features
        in a transparent way (i.e., so the programmer can use them from
        source code without writing something that would be unnatural from
        the source-language perspective).


  5. Don't worry too much about how long it takes to compile, as the
        programs are likely to be short.
