Oh, I?m well aware of the history of this patch. :)  I?d love to see it available on the platforms I use, and agree it?s well worth someone?s time to continue to shepherd this through the processes to make that happen.  Even if it did take years to roll out, Python could use it with the proper compile-time checks.
