Svex-svex-memo

Svex-svex-memo-fix

(svex-svex-memo-fix x) is an fty alist fixing function that follows the fix-keys strategy.

Signature
(svex-svex-memo-fix x) → fty::newx
Arguments: x — Guard (svex-svex-memo-p x).
Returns: fty::newx — Type (svex-svex-memo-p fty::newx).

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