Subject: closure's self

Curious thought --- what if I'd like to know the arity of the proc being 
executed?

  proc{|x| arity }.call(1)

I see no way to do this, not even with the extended Binding class. I begin to 
wonder (for this and other reasons) if a closure's "self" is doable? (at 
least I think _closure_ is the right "scope" for this)

  proc{|x| this.arity }.call(1)
