Paolo, so beautiful it makes me weep. Thanks a bunch :)

I ended up going for a redundant combo solution, in case I wanted to use 
more than one way:

  class Project
    ...
    statuses.each_with_index do |_status, i|
      define_method("#{_status.to_s}?") do
        self.status == i
      end
    end

    def status_is(sym)
      statuses[self.status] == sym
    end
    ...
  end

...and using humanize for the form.

Logan: Thanks, but that won't give me numerical values like I want (I 
want the indices stored in mysql, this is a rails app). I can see how to 
apply that to my case though.
