I would just call that overloading based on number of arguments
A multimethod is a mehtod that is overloaded based on types of arguments.
Moreover,
the types of the arguments are based on the dynamic, not static, type.
method foo( Derived1 $x, Derived2 $y ) { }
method foo( Derived2 $x, Derived1 $y ) {}
my Base $x = new Derived1;
my Base $y = new Derived2;
foo( $x, $y );
foo( $y, $x );
Since foo is a multimethod, the correct foo gets chosen each time, even
though the static type
of $x and $y is Base.
