David Nadlinger's GSoC 2011 code is now pending acceptance in Apache Thrift:
https://issues.apache.org/jira/browse/THRIFT-1500A couple of people at Facebook and Apache have looked at it, but the reviews of a few more people who know D would be useful. I'll try to make the time to give it a thorough review. If you could, that would greatly help push the patch forward.
Thanks, Andrei
