Support multimethods and subroutine overloading in Perl
Sometimes Perl's standard polymorphic method dispatch mechanism isn't sophisticated enough to cope with the complexities of finding the right method to handle a given situation.
Generally speaking, multiple dispatch is needed whenever two or more objects belonging to different class hierarchies are going to interact, and we need to do different things depending on the combination of actual types of those objects. Typical applications that need this kind of ability include graphical user interfaces, image processing libraries, mixed-precision numerical computation systems, and most types of simulations.
