TypeScript destructuring alias import?

Question

I use namespaces/modules for my application. We have a large application broken into several smaller "modules". They are all compiled together, so we have all references at all times. If i need to access module xy from module z I can simply by using xy . Howevever, I don't want to keep referencing x . Is there anyway I can destructure x into aliased names? For example (this doesn't work, hence my question):

import {y,a,b} = x;

instead of:

import y = x.y;
import a = x.a;
import b = x.b;

Is there something similar I can do to simplify my import aliasing of internal modules?

If the members of the module you are importing are not modules (or a type) import will not work. Use var instead:

module x{
 // stuff
}
var {y,a,b} = x;

I don't believe this exists at this time, however I just opened a proposal on the TypeScript repo asking for type destructuring from a namespace.
