Any instance variable refers to the object currently being self at the

> @tl_instance = "hello ruby"

self here is "main", which is the top level default object

> puts @tl_instance

self here is "main" too

Inside tlc.method, self is the "Tl_class.new" object, which doesn't know
about any @tl_instance.
