A common disturbance of mine is when I want a controller named the same as a model. The standard way of solving this is calling your models for example UsersModel, Users_m, or the likes. This has the unpleasant side effect of making your code look fugly. The other option would be to do the same to the application controllers, but this would affect the URL instead of the code which is probably worse in the end since that would affect the end-user. So what to do?
