Functions should do one thing, and do it well. In general, functions
should not be much longer than 20-30 lines (except for, say, handling
many different cases in a 'switch'-statement). Files should not get to
- big either; if there's more than, say, 800 lines, it probably shows the

Code should compile cleanly
