I admit that what you're doing in the Thrift implementation just makes my brain 
hurt :-)

Our goal here is to make it a hassle free release, and that means stomping out 
any new regressions. The only thing that trumps that, however, is fixing broken 
things in the implementation. Unfortunately, your code was inadvertently relying 
on implementation bugs. My goal is to make all non-circular forward references 
work by switching to a lazy semantic evaluation method, and making as many of 
the circular references as possible work.

I'm relieved you were able to find an easy workaround.

The bugs you (and the others here) have posted are a huge help to making 2.059 a 
better, more hassle-free release.
