I used braces to denote the contents of a reference.
Perhaps there is a more appropriate notation?
Why not just
GHC.Prim.MutVar# <value>
that seems to be the most obvious, if perhaps not the tidyest, way to
present it. Do we really need a special syntax and to hide the real
primitive object here?
Cheers,
Simon
