This error is typically caused by evaluating special forms when the
deliver
keyword
:keep-macros
has been set to
nil
.
Beware of this when interacting with the debugger at delivery levels 2 and higher. The absence of the special forms
quote
and
function
can cause difficulty. You may find the functions
find-symbol
,
symbol-function
and
funcall
useful here. It may also help to keep the
COMMON-LISP
package (and perhaps also the
SYSTEM
package), or specific symbols (with the
:keep-symbols
keyword).
