Objective C Swarm users normally don't think about having a different
object after -createEnd, because they usually don't have a different
object.  The object remains the same, but the method dispatch table is
modified to select the right implementation methods as per by
create-time parameters.

To change the set of methods that are active in Java means switching
objects, so the CImpl/Impl relation in the create-time constructor is
to keep things in sync when the phase switch occurs.

Most using-phase Impl classes also have one or more overloaded constructors
which implement the phase switching magic for the user.  It's only in 
complex cases that the dual nature of an interface is exposed..
