Considering the famous Knuth (or whoever said it) quote Premature optimization is the root of all evil, /me thinks the following:
My code is never finished, hence it's always premature. On the other hand, the actual evolving is optimizing. Optimizing is often disguised as cleaning up code and adding features. The term optimizing is rather vague.
