 For example, it's impossible to add a kind signature on a data type with
 `DataD`.

 In {{{Con}}} I believe it's possible to encode GADT constructor signatures
 using {{{NormalC}}} (haven't tried this yet), but ideally there would be
 another constructor specific to GADTs to go along with {{{RecC}}},
 {{{InfixC}}}, and {{{ForallC}}}.
