Hi, 

There is also the reverse possibility: compatibility super class pure
javascript with the inherit by OpenLayers.Class.

It is only necessary:

A = function () {} / / constructor
A.prototype = {
    ...
    initialize: function () {
        A.apply(this, arguments);
    }
}, / / Prototype definition

Some days ago has started to test this on popups, to see time with larger
objects and inheritance and cross inheritance. Works, but I have not
finished the test of time.

NOTE: Another advantage of pure Javascript is the time of initiation, but
this is even more difficult to measure.

Regards,

Xavier
