You can use the old syntax for class declaration for creating classes, i.e. :
Superclass subclass: #MyClass
instanceVariableNames: 'x y z'
classVariableNames: ''
category: 'MyProject'
However, the compiler does not take slots into account yet, so custom slots
will only be available for Pharo 4.
There is a still some work to do in the new class builder and in the slot
architecture to make it usable.
