David, I'm trying to understand your most recent changes but I'm not quite getting the Sealed type. I understand, Sealed (Patch C(x,)) makes the 'y' existentially quantified, which basically hides it, but I don't understand why that's needed. I think the only place I was studying the use so far was in Read.lhs.
Is there a paper or talk I can study to develop a better understanding? Thanks, Jason On 6/15/07, David Roundy <[EMAIL PROTECTED]> wrote:
Hi Eric, This is a rather massive set of patches, which brings you up to our current state of gadt-integration. It also defines the Conflicted patch type, but doesn't create it, so this should be safe.
