Comment (by goldfire):

 The next step should be making a formal proposal on the wiki and gathering
 comments about concrete syntax and such. No one has yet formally
 volunteered to implement, though I was thinking about it. Happy to cede,
 though. Thanks!

 As a response to @dmcclean: The original `data constructor` syntax works
 well with GADT constructors, because the full type of the constructors is
 included after the `::`. I still favor my original syntax, but it already
 looks like I'm in the minority. :)
