So maybe the declaration could be fixed to show that, e.g., as either of:

    name () compound-command [redirection]
    function name [()] compound-command [redirection]

I can't see how to put that in one construct...

BNF would use:

< 'function' <NAME> > | < <NAME> '()' > <compound-command> [redirection]

(ignoring that it would probably also specify <SPACE> where needed

maybe using bash syntax:

+(function _name_ | _name_ () ) compound-command [redirection]
