Escape-to-common-lisp

Escaping to Common Lisp

Example:
ACL2 !>:Q

There is essentially no Common Lisp escape feature in the ACL2 loop (see lp). (A potentially unsound exception is raw-mode; see set-raw-mode.) This is part of the price of purity. To execute a form in Common Lisp as opposed to ACL2, exit lp with :q, submit the desired forms to the Common Lisp read-eval-print loop, and reenter ACL2 with (lp). WARNING: Doing so is potentially unsound; see q.
