Get the after field from a hex-frac-const.
(hex-frac-const->after x) → after
This is an ordinary field accessor created by fty::defprod.
Function:
(defun hex-frac-const->after$inline (x) (declare (xargs :guard (hex-frac-constp x))) (declare (xargs :guard t)) (let ((__function__ 'hex-frac-const->after)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (str::hex-digit-char-list-fix (cdr (std::da-nth 1 x)))) :exec (cdr (std::da-nth 1 x)))))
