I posted to the DM group, thanks for the suggestion.
My colleague suggested an interesting workaround that Merb could
implement:
class Object
def real_class_name
class.to_s
end
end
class Proxy
def real_class_name
parent.class.to_s
end
end
And then #resource would use real_class_name instead of class_name.
