Comment(by jstolarek):

 I just had this thought: how about we use the names of existing primops
 for wrappers and give new names to modified primops, e.g.:

 {{{
   gtCharW# :: Char# -> Char# -> Word#   -- Primop, new name
   gtChar#  :: Char# -> Char# -> Bool    -- Wrapper, old name
 }}}

 This way the change will be backwards compatible.
