Comment (by goldfire):

 Yes, you got it. I agree with your analysis. But it all makes me wish we
 had a more regular syntax for these declarations. Between classes,
 datatypes (with two syntaxes), and type families (both associated and
 not), we just have a veritable zoo of special cases. This is not a problem
 to solved right now, right here, though.
