ghc-mod info only works for main

Question

So I have a very basic haskell file that looks like this :

main = thing
thing = print "hi"

When I run the ghc-mod command to get info on the main function like this : 'ghc-mod info file.hs main', I get the proper result :

main :: IO () -- Defined at file.hs:1:1

But then if I try 'ghc-mod info file.hs thing', it doesn't output anything at all, not even a blank line or error. I have version 5.2.0.0 of ghc-mod, and version 7.8.3 of GHC. How can I get ghc-mod info to work?

显然， ghc-mod需要您在源文件的开头放置一个module Something where ，以使其正常工作。
