Teach :print to follow references (STRefs and IORefs)

Prelude Data.IORef> :p l
l = (_t4::Maybe Integer) : (_t5::[Maybe Integer])
Prelude Data.IORef> p <- newIORef l
Prelude Data.IORef> :p p
p = GHC.IOBase.IORef (GHC.STRef.STRef {((_t6::Maybe Integer) :
                                        (_t7::[Maybe Integer]))})
Prelude Data.IORef> :sp p
p = GHC.IOBase.IORef (GHC.STRef.STRef {(_ : _)})

I used braces to denote the contents of a reference.
Perhaps there is a more appropriate notation?
