// Normal null checking
Outer outer = new Outer();
if (outer != null && outer.nested != null && outer.nested.inner != null) {
    System.out.println(outer.nested.inner.foo);
}

// Safer
def resolve[A](x: A): Option[A] = Option(x)

Option(new Outer()).flatMap(x => resolve(x.nested)).flatMap(x => resolve(x.inner)).map(x => System.out.println(x))

1. After installing GHC, checkout ghc-mod (https://github.com/kazu-yamamoto/ghc-mod) and build master using 7.10.1

2. Update your PATH to include the locaiton of the built 'ghc-mod' and 'ghci-mod' binaries

3. Update your emacs config to load up PATH to correctly locate ghc-mod. I needed to add some elisp to my emacs config

;; Some shell variable magic
(let ((path (shell-command-to-string ". ~/.zshrc; echo -n $PATH")))
  (setenv "PATH" path)
