How do you implement 'written-shared', 'pretty-shared', and
'trimmed/lazy'?  In particular, how do you avoid non-termination when
asked to print cyclic data, when the cycle includes a non-standard data
type printed using a custom printer?  For example, what if you print a
list that includes an object whose custom printer will print output that
includes the same list that you started with?
