I don't think this comment is naive at all - code in a style that seems 
clear to you, but bear in mind that if you expect performance to be an 
issue, the innermost loops should use FP if at all possible.

Often the only way to unpick really complex expressions, is to select 
successively larger pieces (using Ctrl-. ) copy them somewhere, and see 
how they evaluate.
