Can we all agree that Haskell is a pure functional language. I think we must
because: a) it says it is, and b) it is.
f2 = print "Hello World."
f1 = f2
main = do
f1
result of running this:
GHCi, version 8.0.1

OK so Haskell uses monads and Clojure just uses the JVM I/O. Haskell is pure,
Clojure is impure. But I stand by my original statement: Clojure is best used
as a pure language.
Even if I/O is impure, you can make it pure with monads if you really have to.
