only by the look of things ;-) (thats what I meant in P.S.) actually those tokens are not allowed:

bash-5.0$ cat /tmp/m.sh
foo()
() ()
{
        function body
}

bash-5.0$ . /tmp/m.sh
bash: /tmp/m.sh: line 2: syntax error near unexpected token `)'
bash: /tmp/m.sh: line 2: `() ()'

 I am sure function_newline_list can be rewritten in a better way though.

cheers,
