Here's an example:

---------------
@tl_instance = "hello ruby"
puts @tl_instance

def tl_method
   puts "from tl_method -- @tl_instance: #{@tl_instance}"
end

tl_method

class Tl_class
   def tlc_method
     puts "from tlc_method -- @tl_instance: #{@tl_instance}"
   end
end

Tl_class.new.tlc_method
------------

In tlc_method, I am unable to access @tl_instance. Presumably because
it's an instance variable in some other class not Tl_class. But who's
instance variable is it? Kernel? If so, how do I access it?
