The current MMD scheme is strictly 2-dimensional and it is totally
static. It is not suitable for supporting Perl6 in it's current form.
1) summary of current state
MMD (multi method dispatch) is used to find a method for binary
operations like add or cmp depending on the classes (or types) of

2) n-dimensional MMD
Perl6 supports a more general form of MMD:
multi sub foo(ClassA $a, ClassB $b, ClassC $c : ...) { ... }

4) Proposed changes:
a) All method lookup goes through VTABLE_find_method. To achieve MMD
functionality, two arguments are added to the

Lets have two scalars variables in Perl and some operation under
them like an adding.
x = a + b
I would like know, witch auxiliary variables are creating
on the in-line code like a Parrot
somethink like T = a + b
x = T ???
and on witch circumstances depends it.

makes things much clearer for both the programmer and the machine.
Does this imply that it's now possible to type Cmy @foo[23] = 42;, and
declare @foo? In the current perl, this doesn't work -- it's a syntax
