What are the parameter signatures of the macros? The docs (and code) just 
takes *args, so it's hard to figure out.

How can I do the following? Specifically, how can I name the inverse 
"belongs_to" distinctly for :good_bs and :bad_bs?

class A
  has_many :good_bs, B
  has_many :bad_bs, B
end

Thanks.
