Magic goto

• These two are almost the same:

        sub AUTOLOAD {                sub AUTOLOAD { 
          return &blue;                   goto &blue;
        }                             }              

• On the right is magic goto.

• Calls blue normally

• But blue returns directly to AUTOLOAD's caller

• Just as if AUTOLOAD had never been called

• Magic goto is perfect for autoloaded functions
