JS variable shadowing

[ncannasse]

package foo;

enum E {
    Flags( v : String );
}

class Main {
    static function main() {
        var foo_E = null;
        var f : foo.E = Flags(""); // runtime error 
        trace(f);
    }
}

The foo_E variable will shadow our foo.E enum, this error has been introduce by package flattening

This might be difficult to fix. It's easy in the specific case you reported because we can find the E type in the local module, but it might very well be defined in a completely different module. This would then require browsing all types to find potential conflicts.

I guess we can do that as a preparation step for rename_local_vars.
