Yes, but e.g. in exec.c there is a comment
                /*
                 * Remove the old node explicitly in case it has
                 * an alternative name
                 */
I know most of what's going on there, but "functions -c" is creating
an alternate name, and there is also the failure case of settrap()
returning nonzero to handle.
