Yeah, it was a difficult decision to remove types - I'd gotten myself into a corner trying to tack on dependent types, and it just wasn't happening. My bet is that unlike most of the un{i,}typed languages out there (most of which I'd categorize as lisps and smalltalks), tulip provides tagging and destructuring that allows the programmer to maintain some level of control over the polymorphism. Tulip will panic at runtime for non-total functions, but ideally you'll have the tools necessary to keep the panic as close to the problem as possible.
