also you will still have an error if using the RBNamespace instead the direct
method invocation, if class does not exist.
So… I stand with my opinion :)
If you want to control existence, you could do something like this:
#Model asClassIfPresent: [ :class |
class compile: 'asString ^ String empty' classified: #accessing ]
