Is there a more definitive list of reserved words in Rails than the one at http://wiki.rubyonrails.org/rails/pages/ReservedWords ? While it's nice to read war stories of Wiki users running into these issues, it might be nicer to get a canonical, using-these-variable-names-is-asking-for-trouble list from the developers.
As an example, I had a model "Build" (as in a software build) in my app that didn't play nice with the ActiveRecord association creator of the same name.
