Comment (by Iceland_jack):

 Another example of Core from
 [http://osdir.com/ml/general/2016-01/msg29309.html ghc-devs]:

 >> It’d probably need a built-in function
 >> {{{#!hs
 >> setCallStack :: CallStack -> (AppendsCallStack => a) -> a
 >> }}}
 > Correct. This is easy to write in Core but not in Haskell. We also need
 > something similar for Typeable, when we get a type-indexed version of
 TypeRep
 > {{{#!hs
 > withTypeable :: TypeRep a -> (Typeable a => r) => r
 > }}}
