Dimb-scope

Dimb-scope-fix

(dimb-scope-fix x) is an ACL2::fty alist fixing function that follows the fix-keys strategy.

Signature
(dimb-scope-fix x) → fty::newx
Arguments: x — Guard (dimb-scopep x).
Returns: fty::newx — Type (dimb-scopep fty::newx).

Note that in the execution this is just an inline identity function.
