   “One of my favorite transformations is to use threads to confuse a hacker who is trying to steal code. […] Many of the transformations I've discussed go against the programmer's natural sense of what's good and right […] You also don't have to defactor (see the section "Removing Programming Idioms") if you don't want to; you can refactor too. Refactor two similar classes into a parent class, but leave behind a buggy version of one or more of the refactored classes.”
