From a plain invocation of ghci:
{{{
$ ghci
GHCi, version 7.2.1: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.

unknownNameSuggestErr UnhelpfulSpan

}}}
Presumably, ghci wants to suggest the `it` variable but is getting
confused because that variable wasn't defined in a source file.
Note that this doesn't actually crash ghci; the prompt resumes as normal
after the error message is printed out.
