With this much complexity, my temptation would be to provide a
print-readable function (or an optional argument to an existing printer)
that signalled if it were asked to print something that has no read
syntax. Of course, this could be done in Lisp by recursively checking the
type of every element of every sequence, but that would traverse the tree
twice and would fail on circular structures unless `print-circle' were
duplicated within it.
