       SUPER - control superclass method dispatch


       Find the parent method that would run if this weren't here:

           sub my_method
               my $self = shift;
               my $super = $self->super('my_method'); # Who's your daddy?

               if ($want_to_deal_with_this)
                   # ...
                   $super->($self, @_)

       Or Ruby-style:

           sub my_method
               my $self = shift;

               if ($want_to_deal_with_this)
                   # ...

       Or call the super method manually, with respect to inheritance, and passing different

           sub my_method
               my $self = shift;

               # parent handles args backwardly
               $self->SUPER( reverse @_ );


       When subclassing a class, you occasionally want to dispatch control to the superclass --
       at least conditionally and temporarily. The Perl syntax for calling your superclass is
       ugly and unwieldy:


       especially when compared to its Ruby equivalent:


       It's even worse in that the normal Perl redispatch mechanism only dispatches to the parent
       of the class containing the method at compile time.  That doesn't work very well for
       mixins and roles.

       This module provides nicer equivalents, along with the universal method "super" to
       determine a class' own superclass. This allows you to do things such as:

           goto &{$_[0]->super('my_method')};

       if you don't like wasting precious stack frames.

       If you are using roles or mixins or otherwise pulling in methods from other packages that
       need to dispatch to their super methods, or if you want to pass different arguments to the
       super method, use the "SUPER()" method:

           $self->SUPER( qw( other arguments here ) );


       This module provides the following functions and methods:

           This function calls the super method of the currently-executing method, no matter
           where the super method is in the hierarchy.

           This takes no arguments; it passes the same arguments passed to the currently-
           executing method.

           The module exports this function by default.

           Note: you must have the appropriate "package" declaration in place for this to work.
           That is, you must have compiled the method in which you use this function in the
           package from which you want to use it.  Them's the breaks with Perl 5.

       "find_parent( $class, $method, $prune, $invocant )"
           Attempts to find a parent implementation of $method starting with $class.  If you pass
           $prune, it will not ignore the method found in that package, if it exists there.  Pass
           $invocant if the object itself might have a different idea of its parents.

           The module does not export this function by default.  Call it directly.

       "get_all_parents( $invocant, $class )"
           Returns all of the parents for the $invocant, if it supports the "__get_parents()"
           method or the contents of @ISA for $class.  You probably oughtn't call this on your

           Calls the super method of the currently-executing method.  You can pass arguments.
           This is a method.


       Beware: if you do weird things with code generation, be sure to name your anonymous
       subroutines.  See Perl Hacks #57.

       Using "super" doesn't let you pass alternate arguments to your superclass's method. If you
       want to pass different arguments, use "SUPER" instead.  D'oh.

       This module does a small amount of Deep Magic to find the arguments of method calling
       "super()" itself.  This may confuse tools such as "Devel::Cover".

       In your own code, if you do complicated things with proxy objects and the like, define
       "__get_parents()" to return a list of all parents of the object to which you really want
       to dispatch.
