fwiw, we could fix our "type parser" for "JS" to understand generics...

I've wanted to fix it for a while because it's *so* dumb right now (doesn't even
understand how to look up the type name from anywhere but core!)

[vsm, 2015/08/07 17:07:33]

Up to you.  We don't really use it so much I guess - unless we make a version of
this available to users.

     _metadata = (fn == null)
         ? <InstanceMirror>[]
         : new List<InstanceMirror>.from(fn().map((i) => new JsInstanceMirror._(i)));

make this a getter? (less storage needed on the instance)

[vsm, 2015/08/07 17:07:33]

Could be ... but won't a constant for long ... so maybe not worth it.
