Foxy fixtures (http://ryandaigle.com/articles/2007/10/26/what-s-new-in-
edge-rails-fixtures-just-got-a-whole-lot-easier) are great for new
projects, and I'd like to refactor fixtures in existing projects to
make them foxy, but find it quite a chore. I'm considering a simple
plugin to ease this task; has anyone already taken the effort to do
something like this?
