FORWARD CLASS(SUPER) will forward the method using the instance method
dictionary for the immediate superclass of the issuing method. If you
issued that from either MixinA or MixinB, this would result in an error,
since Class2 (the immediate super class of both mixins) does not implement
a doIt method. Forward does not need to go directly up the inheritance
chain, however. I can also step over to another part of the tree. For
example, you could use
FORWARD CLASS(.MixinB)
in the doIt method of MixinA go get both methods invoked.
