Comment (by simonpj):

 Remember:

  * Most things that use `Typeable` will continue to work un-modified.  The
 class has not changed its kind; and the functions `cast`, `gcast` etc
 continue to work with the same signatures.

  * I believe that only a relatively small number of packages (mostly
 Edward K's) decompose `TypeRep`; in fact, Richard I think you did a small
 study that discovered this.

 The story is already quite complicated.  Making it more complicated still
 with a back-compat shim is undesirable unless it is absolutely necessary.

 First thing is to nail the API etc; then we must discuss transition.

 None of this is going to land until after 8.0
