Re: list operators

Thanks to all of you for your quick answers! But let my summarize and
the take the discussion a little further:

    1) It is too late to introduce changes

It's not really a change since it doesn't change the semantics of existing,
valid scripts.

    2) The syntax is bad

Yes !! Maybe its an alt.tasteless candidate.

    3) A semantic improvement

I should have thought of that! Of course,
    ; x = ( 1 2 3 4 ) echo $x( -1 -3 )
    2 4
is much better.

    4) Why not use a function

Thanks to all who disclosed their solutions, but I already had some. I think,
there's more then one point of view to it:
Experienced rc users certainly don't have problems to write a function doing
the work, to put it in some kind of library and to reuse it on other occasions.
But the notion of "omit it if you can write a function" doesn't help novices
and - be honest to yourself - isn't it boring that you always have to source
some other file to include a function in your script ( . /some/file || exit )?
So it's speed and beauty vs usability. I'm still convinced my suggestions
enhance both.
