What I'm having trouble understanding is how $class is passed the

speak.
It's automatic when you use the method syntax. If you called a
subroutine in the normal way, perl would leave your argument list
alone. But when you make a method call, perl adds the class name (or
blessed object) as the first parameter.
# Without method syntax, manually include the class name
&Horse::speak("Horse");
# With method syntax, perl adds it for you
Horse->speak();
Hope this helps!
