Subject: help with tricky proc/binding issue


i'm trying to be able to define a proc that can be called in the context of
self, eg:

   block = lambda{ p 42 }
   an_obj.instance_eval &block

but which can also be called with arguments, for example (imaginary ruby):

   b = lambda{|x| p [x, y]}

   class C
     def y; 42; end
   end

   c = C::new
   x = 42

   c.arg_instance_eval(x, &b)  #=> [42, 42]

any ideas?
