If it's not, that's a | bug! I thought that inferred foralls are Invisible binders (see Note [TyBinders and VisibilityFlags]); and you can't use visible type application for Invisible binders. I thought that was because it's hard to specify the order of inferred type variable, just as Ryan says. So /is/ inference meant to give a reliable ordering? If so why? Also I don't understand why Ryan needs a reliable ordering. So you can see I'm a bit confused here Simon
