Is there any plan to get rid of the lower-case property names in a HopObject?

I know it's not a general issue because all properties are generally
accessible:

var h = new HopObject;
h.FOO = "bar";
res.debug(h.FOO === h.foo); // true

However, when looping over a HopObject one gets only the lowercase property
names:

var o = new Bar; // assumed there's a mapping for FOO in Bar.properties
for (var i in o) {
   o[i] = h[i]; // o.FOO will *never* be set, onl o.foo which is unmapped
}

This leads to unwanted results e.g. when using output via Xml.write/read for
exporting and importing data between two applications.

What about an application-wide switch for enabling/disabling mixed-case
property names in HopObjects?
