Show data/type family instances with ghci's :info command

Current version of ghci (7.6.3) does not show data instances. For example, I have some Yesod application and I want to see all data constructors of (Route App) data family instance:

*Application> :info Route App 
class Eq
        (Route
           a) => yesod-routes-1.2.0.6:Yesod.Routes.Class.RenderRoute a where
  data family Route a1
  ...
        -- Defined in `yesod-routes-1.2.0.6:Yesod.Routes.Class'
instance Eq (Route App) -- Defined at Foundation.hs:48:1
instance Read (Route App) -- Defined at Foundation.hs:48:1
.................

It just shows info about Route, then info about App separately. When I try this:

*Application> :info (Route App)

<interactive>:1:2: parse error on input `Route'

I am getting parse error.

I offer to use this syntax (with parentheses) to show info about instance of data/type family, namely, data constructors and such stuff, just like for ordinal data.
