Gack!  @ is ugly as sin to me.  Why not allow function attributes as 
keyword arguments
using the decorator syntax.  e.g.,

  def foo(self, a) [classmethod, precondition=predicate1, 
postcondition=predicate2,
                                             bnf= 'FOO := left op right']:
     pass


Thoughts?
