```nohighlight

module RRW
  struct YU
  end
end

const modsym = RRW

getfield(modsym,:YU)

```

ERROR: UndefVarError: YU not defined

this doesn’t happen when i do the following:

```nohighlight
getfield(RRW,:YU)
RRW.YU

```

Why does this happen?

Works fine on 0.6.3 as well, so maybe just upgrade to that if it’s not working on 0.6.2?
