MirBSD's ksh allows all three forms but treats `function name()' like
`name()', that is $0 stays the same and will not be set to the funtion's
name:

        $ echo $KSH_VERSION
        @(#)MIRBSD KSH R57 2019/03/01
        $ function f { echo $0; }
        $ f2() { echo $0; }
        $ function f3() { echo $0; }
        $ typeset -f
        function f {
                \echo $0 
        } 
        f2() {
                \echo $0 
        } 
        f3() {
                \echo $0 
        } 
        $ f
        f
        $ f2
        mksh
        $ f3
        mksh
