Currently meaning this will change predictably? Let me just say this is
quite nice, and I'll have to implement something like this in our Domain
classes _soon_. My question is:

Does the typesystem offer any introspection? I.E., can I in runtime
discover the attributes registered for my class, and what types they are?
I need this for type-checking when sorting columns in my UI framework, so
that would come in handy.

Oh, this _is_ a runtime typecheck? :)

How's it going?

Ok, assuming this will be released, can I go ahead and docstring my
classes and assume I'm going to be able to do the runtime checking when
it's available? I had devised a complete typesystem based on dictionaries,
but if yours is ready and tested, I'll chuck mine.

Take care,
