Care to extend on that "polymorphic signature trick"?

• aardvark179 10y ago
  There is an annotation that can be used in the JDK to mark methods as polymorphic. The compiler will declare the method call with the types of the arguments and result where it is called, and the VM will handle it. This allows a very small set of core methods to take variable numbers or types of arguments without boxing them or having to put them in an array.
