Everybody, just stop with calling #scalaz' unsafePerformIO. Use this: https://github.com/scalaz/scalaz/blob/scalaz-seven/effect/src/main/scala/scalaz/effect/SafeApp.scala … - now you're closer to #Haskell

@puffnfresh So long as your program is single-threaded, you're fine. But try to use Future, and you end up forced into unsafePerformIO.

@nuttycom @puffnfresh provide Forall[Future, IO] and you're golden.

@dibblego @puffnfresh What does that mean? What does this incarnation of Forall look like?

@nuttycom @puffnfresh trait Forall[F[_], G[_]] { def apply[A](x: F[A]: G[A] }
