I've also been wondering whether we want pretty-printing at both the
value_ and the val_ layers.  It seems a bit weird.

That is odd.

We could keep a hash of values that we have seen and throw an
exception if one is reused.  This is a mild pain due to the val_print
code.  Alternatively we could avoid recursion by disabling
pretty-printing the second time.
