Major Section: HONS-AND-MEMOIZATION
This documentation topic relates to an experimental extension of ACL2 under development by Bob Boyer and Warren Hunt. See hons-and-memoization.
The value of (hons-let form) is the same as the value of
form. However, in the former case a new hons environment is
temporarily created, where no hash conses are stored. The
pre-existing hons environment is restored upon exit from the
evaluation of a hons-let expression.
We may write more on this topic, especially upon request.
