Why not allow the spread operator to appear earlier (still just once
though) in ArrayPatternList in
http://wiki.ecmascript.org/doku.php?id=harmony:destructuring? This
could be useful when there is interesting stuff at the end and not
interesting and/or variable length stuff earlier
// variable length early segment
function(first, ...variableLength, last){}
// not interesting early segment
function(interesting, ...notInteresting, alsoInteresting){}
// identifier omission may be useful in this case
function(interesting, ..., alsoInteresting){}
// array literal forms
[first, ...variableLength, last] = arr;
[interesting, ...notInteresting, alsoInteresting] = arr;
[interesting, ..., alsoInteresting] = arr;
Thanks,
