At the top level 'self' references the same object in the file scope
and in the method scope (really private instance methods of the top- 
level
object).  Why then is it puzzling that the instance variables are
accessible from either place?


   @a = 'this is @a'
   puts "top: self: #{self.object_id}"
   puts "top: @a: #{@a}"

   def foo
     puts "foo: self: #{self.object_id}"
     puts "foo: @a: #{@a}"
   end
   foo

put that code in a file and run it:

top: self: 1019060
top: @a: this is @a
foo: self: 1019060
foo: @a: this is @a
