That is not what I said.  I said that you, the script writer, can check
whether or not a filename containing a slash is executable before
attempting to execute it.  Maybe a function something like this (untested):

        case "$1" in
        */*)    ;;
        *)      "$@"  ; return $? ;;

        if [ -x "$1" ]; then
                other-prog "$@"
