The following illustrates two lisp reader bugs:
the first one is a bug on reading a simple reentrant structure,
the second one is a bug on reading symbols matching *B* or *b*
where * is any (large enough) number. We have looked at
the reader code for the 1st bug and did NOT find an easy fix.
Good luck!
Except for that AKCL is really neat stuff! Congratulations!!
