Support for type of

[uittorio]

typeof is not currently supported and it would be nice to implement the correct value.

Example

var obj = {
   a: ''
}
interface Interface {
    typeOf: typeof obj;
 }

The result of typeOf should be the var obj with default values.
A solution would be to generate the literal type on the fly and keep in the correct scope
I am not sure yet about all the implementations and how to solve it because there are scenario that a bit more complex. For example typeof of an enum type.

This issue needs to be investigated.
