Fixes #30

Thanks for the pull request. This change looks good to me. We vendor go/loader using godep, and we should update that repository to. If you want to update go/loader, let me know, otherwise I can make that change.

As it turns out, go/loader is not currently vendored. That's what caused the install to fail. Since it's not vendored, go get fetches the fresh version from github on every install.

When I deleted and regenerated all of the dependencies with godep save I got the following error.

godep: Godeps/_workspace/src/golang.org/x/tools/go/loader/testdata/badpkgdecl.go:1:34: expected 'package', found 'EOF'

Looks like there is an intentional error in a .go file in the go/loader package resulting in godep failing to parse it and bailing out before completing the copy. I can manually update the vendored files, but it will likely fail every time it's rerun.

Ah, that's weird. Let me merge this in, then, and you should file that error as a bug report against godep. Thanks again for the contribution!
