>Programming won't be a 'professional' occupation until such time as it can be removed from the realm of art and placed into the realm of science.

Medicine is an "art" as well as a science. Things like choosing the right medication may be science in that certian antibiotics will only work against certian bacteria. It's an art in the sense that choosing a once-a-day dose of a somewhat less effective medicine may work better for a certian patient than a multi-dose medicine that the patient will forget to take.

Programming is the same. Do you always write for mazimum efficiency? Do you sometimes write for readability, or because you are more comfortable doing things the tried-and-true (for you) way?
