Now why wait for 3.0? This can easily be wrapped into OpenLayers.Class (and
that's what I was hoping for when I meant "OpenLayers.Class has room for
improvement"). I have just created http://trac.osgeo.org/openlayers/ticket/2899.
Some results with the patch I have attached to that ticket, which basically
turns OpenLayers.Class into "Pure JavaScript":
Safari 5:
OpenLayers.Class 15.65
Pure JavaScript 19.1
Object Litteral 13.7
Firefox 3.6.10:
OpenLayers.Class 63.7
Pure JavaScript 60.15
Object Litteral 62.1
Regards,
Andreas.
