we intend to introduce namespaces to ObjM2 and ideally do so in a
way that ObjC classes will also benefit from this. It would be
great if somebody with insights into the Mach-O format and the ObjC
runtime could give some feedback or even join our discussion on
this topic.
So far the idea is to allow classes to be bundled into a library
module and add a facility for the library module to rename the
classes as it exports them, which would cause them to be added to
the ObjC runtime under their "rebranded" name instead of their
original name.
[snip example]
It would seem that this should be possible to do, but we are not
sure about that. We'd appreciate some comments on this, mainly as
to feasibility in general, not necessarily in respect of how to do
it, because at this point the goal is to design a language
extension. Implementation is further down the road.
thanks for any feedback

So how would NSClassFromString handle having the classes being
renamed? You could, in theory, find the static strings and change
them (ugh), but anything which uses a string constructed on the fly
would fail (since the constructed name no longer matches).
And this approach seems to have the insidious side effect that the
original code (that which existed before being rebranded) has no way
to know that this is happening (since there is that module that takes
the original classes and then actually does the rebranding).
Personally, I'd investigate a C++ style namespace (which would be
built on a prefixing scheme, rather than renaming, so
NSClassFromString could be modified to know the 'current' classname).
