Also, there seems to be some change in the :NAMED option whereby if a kind
of structure used to be called COORDINATE-PAIR, a user-provided function
called COORDINATE-PAIR would be sent a :PRINT msg when one had to be printed,
but now the printer just prints #<COORDINATE-PAIR 1234567>. If this is
an incompatible change, where is documentation on it?
This probably is the result of fixing a bug in print. It sounds like your
function does not handle the :WHICH-OPERATIONS message. Up to date
documentation on this may be found in the "named structure" section
of the file AI: LMMAN; DEFSTR >.
