Alright, it's maybe a bit hyperbole. If I'm thinking about what characterises Haskell, it's not that it has closures, it's that it makes control flow and side effects explicit through monads. Blueprint has a very similar idea where effectful/stateful code is ordered sequentially through the white lines, while pure functions are hooked up just through their inputs and outputs. It doesn't go much deeper than that, but looking at Haskell it seems blueprint really might go a lot deeper.
