this is a double edged sword. you *do* get it right *if* you think it through, but reality is often more complex than you assume. if you suddenly see that you forgot to handle special case x, you are punished harder than in <random statically typed oo language>. in oo, you can do a few "emergency hacks" before everything becomes unmaintainable. in clojure, i could not do this without committing maintenance suicide immediately. for each case that popped up surprisingly, i had to do a bit of refactoring. that whole "dynamically typed" thing is creeping me out. > > To put it another way, how much refactoring we we do in Java is > down to managing the complexity of the problems inherent in Java > the language; complecting state and identity for example. > > A concrete example: I know I often refactor code out of one class > into a utility once that becomes useful by other classes.
