The autobox pragma allows methods to be called on integers, floats, strings, arrays, hashes, and code references in exactly the same manner as blessed references. The autoboxing is transparent: boxed values are not blessed into their (user-defined) implementation class (unless the method elects to bestow such a blessing) - they simply use its methods as though they are.
