Clone default objects

[justinbmeyer]

I would like to be able to do:

DefineMap.extend({
  items: {default: []},
  data: {default: {foo: "bar"}}
})

And have it clone the default object/array. This would no longer warn because the value would be copied. This would be a breaking change.

I'd also like to be able to do:

DefineMap.extend({
  items: {default: []}
  data: {foo: "bar"}
})

And have it do the same thing. However, this would be another breaking change.

Other considerations:

• what happens if something like window is passed? We can't clone that. We only clone POJO objects?
• Do we clone objects deep?
