Subject: Re: scope when reopening method

Yes, you have misunderstood. "meth" already has access to its own 
variables.
There is an application that creates an instance of My.
It also contains an array "arr". I'd like to refer to that array within 
the reopened "meth".
I would also like to call some methods that are in my app from the 
reopened method.

   # i create an array that is not inside My class. Its in my 
application.
   arr = []

   # this method belongs to my app, not to My class
   def do_something str
     puts str
   end

   m = My.new
   def m.meth(str)
     # access some other object in application scope
     # arr can be instance variable or local variable in application
     arr << str
     do_something str # call some method in my app
   end

Hope i am clear. thx.
