As an important corollary to this one I would add: "never throw
exceptions from pure code". They often leak out from "catch" blocks and
ruin your day.

It's not possible to throw exceptions from pure code. You can only call 'error' 
and that's another name for 'undefined', i.e. you have a partial (non-total ?) 
function.
