set the default hints
Major Section:  EVENTS

Examples: (set-default-hints '((computed-hint-1 clause) (computed-hint-2 clause stable-under-simplificationp))) (set-default-hints nil)

Note: This is an event! It does not print the usual event summary but nevertheless changes the ACL2 logical world and is so recorded.

General Form:
(set-default-hints lst)
where lst is a list. Generally speaking, the element of lst should be suitable for use as computed-hints.

Whenever a defthm or thm command is executed, the default hints are appended to the right of any explicitly provided :hints in the command. The hints are then translated and processed just as though they had been explicitly included. Technically, we do not put restrictions on lst, beyond that it is a true list. It would be legal to execute

(set-default-hints '(("Goal" :use lemma23)))
with the effect that the given hint is added to the :hints argument of subsequent defthm events. But that would prevent subsequent defthm events from having an explicitly provided "Goal" hint since it is illegal to provide two hints on the same goal-spec. We strongly recommend that you keep the default hints set to a list of computed-hints.

Note that set-default-hints sets the default hints as specified; it does not merely add to the current default. One might imagine a set of convenient commands for manipulating the current setting but in lieu of any experience with default hints we have implemented only the most basic functionality.
