See things, like this http://en.wikipedia.org/wiki/Qi_%28programming_language%29 or https://github.com/clojure/core.typed

Both of those projects implement fairly simple type systems, they both even look simpler than even ML. Having at least outer rank-1 quantification is what I consider a "modern" typing system.

Im not a expoert. But I think at least Qi is as advanced as haskell or ml. The clojure one is relativly new and not jet full featured.
