Well not to mention the inline filtering which is part of the ease of use for the e4x, but harder to recreate.

The only E4X expression I have used over and over is the ability to get an array of child nodes using the double-dot expression. For example: var mySVG:XML = <svg> <desc /> <rect /> <ellipse /> <path /> <path /> <path /> <ellipse /> <path /> <path /> </svg>; We could write: var paths:XMLList = mySVG..path; I think if we can add support to just this (maybe a few more based on popular usage), we should be able to get existing Flex apps easily ported. Although, I am not sure how hard something like this would be to implement. Thoughts?
