Failing fast to learn a lot

A few weeks back while debating Marvin on the object-composition group we talked about the meaning of ‘this’ in a role method. Today while working on Moby I realized how important it is that self/this point to the role itself inside a role method. It hasn’t bugged me while using Marvin but when using a dynamic language like Ruby where there’s no compiler that will ask “Did you really mean this? because I don’t know what you are trying to do” it’s paramount that the code shows the intention clearly and since DCI is all about clarity this should be reflected in other languages as well. It is already reflected in Marvin, and has been ever since that discussion.
