Text.Hamlet.Runtime - nesting HamletData?

Question

I am rendering Hamlet templates using the Runtime module. The following works as promised with the example data:

let hamletDataMap = Map.fromList
  [ ("name", "Michael")
  , ("hungry", toHamletData True) -- always True
  , ("foods", toHamletData
    [ "Apples"
    , "Bananas"
    , "Carrots"
    ])
  ]

But I can't see any way for me to render nested data. For instance if I have a list of metadata of various fruits, I would like to do something like:

let hamletDataMap = Map.fromList
  [ ("name", "Michael")
  , ("hungry", toHamletData True) -- always True
  , ("fruits", toHamletData
    [ [ ("name", "apple")
      , ("taste", "sour")
      ]
    , [ ("name", "..")
      , ("taste", "...")
      ]
    ])
  ] 

In the Text.Hamlet.RT there is the HDList [HamletMap] which looks kindof strange but still promising. I can creates instances of HDList but it gives me type mismatch HamletData with actual type RT.HamletData url0.

I'm thankful for any ideas or suggestions.
