A Rails (v2.1.0) plugin that tries to solve the problem of having to call a method repetitively. That method is expensive to be recalculated everytime. The solution is to cache the method results and we've always done that by caching a method's result in instance variables. method_cache plugin frees you from the trouble of worrying about writing caching code and introduces a couple of utility methods in ActiveRecord objects that make your life easier.
