Re: feature request: ${@ command; } and ${* command; } funsubs to expand to all elements of the local array REPLY

I'm also interested in this. We already have some functions that
return an array through REPLY in bash-completion (see e.g. Ref. [1]).

I actually suggested the same feature in Ref. [2] with a slightly
different syntax. I chose ${@| cmd; } so that it is distinct from
${<word> cmd; } to keep it for future extension. I discussed it partly
in Ref. [3]. However, ${@ cmd; } is still a possible option.
