Sneaky

Sneaky-incf

Increment a value in the sneaky store.

Signature
(sneaky-incf name &optional (amount '1)) → *
Arguments: amount — Guard (acl2-numberp amount).

Example:

(sneaky-save 'foo 3)
(sneaky-incf 'foo)   ;; increment by 1
(sneaky-incf 'foo 2) ;; increment by 2
(sneaky-load 'foo state) --> (mv 6 state)

In the logic, sneaky-incf just returns nil. Under the hood, we update the sneaky store, incrementing the value of name by the indicated amount. The accumulated values can later be accessed with sneaky-load. See also sneaky-save.
