That seems so obvious now that you say that.

That said, I have better-defined my goal: to conditionally create an 
instance-level method.

Here's my plugin:
http://pastie.caboo.se/178169

Note the recommend method towards the bottom. That method should only be 
available to objects who recommend (who are 'recommenders').

I understand class definitions are active (to use your language, I 
believe ;), but it feels dirty to specify a conditional outside a 
method.

Even if I did use a conditional, I wouldn't have access to the 
information passed in by the including object. E.g...

class Category

  acts_as_recommendation :recommender => true

end

I suppose I could break the plugin in two: acts_as_recommender and 
acts_as_recommendable... =/

Thoughts?
