Aren't refinements a "fixer feature", i.e. something 99% of developers should just ignore it until they really get into a problem with badly done monkeypatching, then use it to solve the problem and just move on? Why do people get so excited about them, both in a good and in a bad way? Just use them inside your library code and make sure people using your lib/framework can just pretend they don't exist, keep monkeypatching "chained inside" as your dirty little secret:P)
