Support nested records about cmdargs HOT 1 OPEN

Hey Neil!

First of all, thanks for CmdArgs, awesome work!

I just encountered this problem, my different modes have overlapping record key names, and in order to make the code a little cleaner and avoid fName, dName, I separated my modes to different files so I could have F.name and D.name. But then I realized I won't be able to create a Sum Type over those without wrapping them in another constructor.
This is what it looks like right now:

-- Main.hs
data Params = WebServerParams W.Params
            | FileSharingParams F.Params
            deriving (Show, Typeable, Data)

-- WebServer.hs
data Params = Params { name :: String } deriving (Show, Typeable, Data)

But then, this does not quite work as CmdArgs looks only one level deep for properties.

Do you have any ideas how I could workaround this problem?

If you think I could fix this issue, please direct me to the related files and I will look into it.

Thanks in advance 👍 😁
