names scopes and boolean methods


We're exploring the new world of named scopes (hooray) and wondered about some functionality.

If I have for example

named_scope :foo, :conditions => {:bar => true, :quux => 2}

which obviously creates a method, would it be possible to automatically generate a method Model#foo? which told you whether an instance of that model was a member of the collection?

The idea is that the named scope would let you do things like

model Article    named_scope :published, :conditions => { :some => :conditions } end

@article = Article.published.first # for the entire model @article.published? # for any given article

Is there any reason this wouldn't be possible?>

Thanks, Gareth
