The 'inheritance mechanism' is the -> operator,

No. The inheritance mechanism applies to method calls. Few of the -> operators have anything to do with methods. For example, 

$x->[0]

Furthermore, not all method calls use the -> operator. For example, 

new Foo

Forms of method calls: 

$class->method(LIST)     # Static method call.
$object->method(LIST)    # Instance method call.
$x->Class::method(LIST)  # Pretend the LHS is class "Class".
$x->SUPER::method(LIST)  # Pretend the LHS is its super class.
method $x LIST;          # Indirect method syntax

I think that's all of them.

Horse::speak("Horse") is a sub call. Subroutines aren't inherited. Subroutines don't have classes, so subroutines don't have parent classes, so subroutines have nothing from which they could inherit.
