Precedence of type-level operators
a ': b ~ c ': d
seems to be parsed as a ': (b ~ (c ': d))
. This is kind of unfortunate; It seems to me that (~) having a lower precedence would make more sense, i.e. have it parse as (a ': b) ~ (c ': d)
.
What //are// the precedences of (~) and XDataKind-lifted operators? The userguide mentions precedences when discussing TypeOperators, but not in combination with DataKinds, or the type-equality-constraint.
