Comment(by batterseapower):

 As the blog post points out (and I recently rediscovered) GHC already
 supports this feature in a more elaborate form. This works:

 ~~~
 {-# LANGUAGE GADTs, Rank2Types, FlexibleContexts #-}

 class Foo a where
 foo :: a -> String

 instance Foo [b] where
 foo = show . length

 data FooDict a where
 FooDict :: Foo a => FooDict a

 f :: (forall b. FooDict [b]) -> String
 f FooDict = foo "Hello" ++ foo [1, 2, 3]

 use_foo :: String
 use_foo = f FooDict
 ~~~

 But this is rejected:

 ~~~
 g :: (forall b. Foo [b]) => String
 g = foo "Hello" ++ foo [1, 2, 3]

 use_foo' :: String
 use_foo' = g
 ~~~

 So there doesn't seem to be a fundamental difficulty here.

 Let's either automatically enable `-fobject-code`, or add a suggestion to
 turn it on to the error message, and then close this ticket as wontfix.
