The trouble:
module A
data ABC = A { a :: String }
| B { a :: String }
| C { a :: String }
module B
data ABC = A { a :: String }
| B { a :: String }
| C { a :: String }
is valid haskell.
so how should you know having the serialized String { a : "abc" }

Hi,
The following piece of code runs just fine, if I say:
instance Random RGB where
random = color
randomR = colorR
instead of:
instance Random RGB where
random = color2
randomR = colorR
When I use random = color2 I encounter a stack space overflow:

Oh thank you both *^o^*... now works like a charm again.
Btw, Cetin, this is good practice, along with -funbox-strict-fields:

Much better code than using a lazy triple.
