The page describes an improved implementation of the Typeable class, making use
of polymorphic kinds. Technically it is straightforward, but it represents a
non-backward-compatible change to a widely used library, so we need to make a

Comments? You can fix typos or add issues directly in the wiki page, or
discuss by email
Where is Proxy data type defined? Which instances should it have?
What API should it offer? Also Edward Kmett wrote package which
implement such type[1].
I'm not sure that typeOf should be deprecated. It's could be useful as
convenience function.
