DO NOT MERGE: Remove || to get it to build

This is just to demonstrate that this change can get the document to build, but it shouldn't be used because we probably want `||` to be in the `Prelude` and indexed.

As an aside, I noted that `||` does not appear in the index of the [Haskell 2010 PDF](http://www.haskell.org/definition/haskell2010.pdf).
