Is there, or has there once been?

final comes after virtual/dynamic. Its supposed to stop you from
overriding
a method. Which is a bit strange because then you should not declare it
virtual to begin with.
A person that overrides virtual methods does not always have control
over whether the method had been declared as virtual. With "final" the
user can tell the compiler that this method won't be overriden anymore
and thus the compiler can change virtual method calls to direct method
calls (assuming the compiler knows the class type involved for sure).
It's similar to the WPO devirtualisation pass the compiler supports just
without the need to compile the code twice.
