 Methods in PIR are subroutines stored in the class object. Define a method with

 divided by two. Notice that the code never declares the named variable C<self>.

 Subroutines acting as vtable overrides must either have the name of an actual

 You must call methods on objects explicitly, but Parrot calls vtable functions
 implicitly in multiple contexts.  For example, creating a new object with C<$P3
