Comment:

 Oh, I also missed it at first, but it's actually there already:

 {{{
 In its default mode, GHC does not accept datatype contexts, as it has been
 decided to remove them from the next version of the language standard.
 This behaviour can be controlled with the DatatypeContexts extension. See
 Section 7.4.2, “Data type contexts”.
 }}}
