In the execution this is an array write, but the logical definition is just a thin wrapper for update-nth:
Function:
(defun update-svexs$ai (stobjs::i stobjs::v svexarr$a) (declare (xargs :guard (and (svexarr$ap svexarr$a) (integerp stobjs::i) (<= 0 stobjs::i) (< stobjs::i (svexs$a-length svexarr$a)) (svex-p stobjs::v) (stobjs::typep$ stobjs::v (satisfies svex-p))))) (ec-call (update-nth stobjs::i (svex-fix$inline stobjs::v) svexarr$a)))
