Destructuring Assignment default value backward compatibility with coffeescript broken

[vird]

{
  interval
  mod = 0
} = opt

coffeescript 1.10.0

var interval, mod, ref;

interval = opt.interval, mod = (ref = opt.mod) != null ? ref : 0;

iced 1.8.0-a (currently on http://maxtaco.github.io/coffee-script/)

Uncaught SyntaxError: unexpected =

error: unexpected =
  mod = 0

I am thinking about moving all work to the iced3 branch, which requires
generators ( or piping output through regenerator / Babel ). What are your
thoughts?

Came here looking for destructured arguments defaults too.

I am a heavy user of iced-coffee-script and would support moving to iced3. Generators are supported in Node since v4 and I'd bet anyone using iced for frontend (like myself) already has a build chain where Babel would be easy to add.

Thanks to coffee-script and Iced, I'm not clamoring for generators or other ES6 features. I know the rest of the JS world is moving in that direction though -- so I think iced3 is the most sustainable way forward, and the simpler syntax and compatibility would help iced adoption.
