Yesterday evening, I took a short stab at analyzing this issue. I
think it's an interaction between the lisp reader/printer assignment
and the way our FASLs work. To be more precise: in DUMP-FORM (used
from the compiler), we don't bind *all* the printer/reader influencing
dynamic values, but rather only a limited number of them.

It'll take more than the 20 minutes I had to analyze the best
solution. I'll come back hopefully later this week.


Regards,


Erik.
