Skipping values/splats in destructuring

[zmthy]

Any takers for the Javascript 1.7 syntax of skipping values?
[a,, b] = [x, y, z]
is roughly
__a = [x, y, z]
a = __a[0]
b = __a[2]
Also, how about splats?
[a, b...] = [x, y, z]
to
__a = [x, y, z]
a = __a[0]
b = Array.prototype.slice.call(__a, 1)

Nice idea. Splats are now allowed in destructuring assignment.

[a, b...]: [1, 2, 3]

Compiles into this:

var __a, a, b;
__a = [1, 2, 3];
a = __a[0];
b = Array.prototype.slice.call(__a, 1);

b becomes [2, 3]

Not adding the skipping-values-with-commas. It's too typo-prone and funky-looking. Closing the ticket...
