> into even more even more complex code. Sure, but there's way less of it. Way less to test, way less to maintain. Also, you can refactor metaprogramming back out of a codebase after you've introduced it. Basically this involves taking the hacks and giving them classes with state. Essentially you're modifying the design of your application without ever introducing a break in continuity of functionality.
