Hi! 
Are there any ways to call the  methods of other objects with self as an
argument ? 
I mean situation like that: 
class foo = object (self)
	val observers : bar list = []
	method register  = 
		Array.iter (function o -> o#register self ) observers
		....   			^^^^^^^^^^^^^^^^^^
end

class bar = object 
	method register ob =
		(* add something *)
end

When i'm trying to write something like that ocamlc says me that 
self canot escape of it's definition
