So, here's the interop story at the moment for Node:

IE9:      typeof Node // "object"
FF4:      typeof Node // "object"
Safari5:  typeof Node // "object"
O11:      typeof Node // "function"
Chrome10: typeof Node // "function"

(It's not as interoperable as I'd hoped.)

There's certainly an argument to be made consistency with ES5 (i.e., change to
"function"), and I get that.

However, interface objects really are not typical constructors--and I think
it's OK for them to be different in this regard. Case-in-point, interface
prototype objects are also not the same as any of the prototypes in native
JavaScript. For example, a "prototype" should be a prototypical instance of the
constructor (e.g., Number.prototype _is_ a number instance, Function.prototype
_is_ a function instance, etc., but clearly the interface prototype object does
not follow these rules either, nor should it IMHO.

Again, I think it's OK for interface objects to be different from a typeof

I think the best path forward is to get Opera's bug fixed and Chrome should be
able to respond quickly given their release cadence. At that point the
high-order bit is interoperability.
