Self-kinded type variable accepted
Found when chasing #11407 (closed)
data T (a::a) = Blah -- Accepted
data S (b :: a) a = ...
-- Rejected with: variable ‘a’ used as a kind variable before being bound
-- as a type variable. Perhaps reorder your variables?
But T
should be rejected too, for the same reason as S
