These are function calls. The only arguments the functions receive are those you pass manually:

Cow::speak;
Horse::speak;
Sheep::speak;

These are method calls. They receive their invocants as arguments, along with any arguments you pass manually:

Cow->speak;
Horse->speak;
Sheep->speak;

You can call methods as functions, but you will break things if you do.
