I have a question about solving obligations generated by Program Fixpoint in the current svn snapshot of Coq 8.2 (r11354). I'm using the documentation at http://coq.inria.fr/V8.2beta4/doc/refman/html/ . Consider the following silly and trivial example. (There's no reason to do this in practice, but it does illustrate my problem.)

It's hard to tell which features of [Program] you are using, since your example is implementable trivially with normal [Fixpoint]. For my own edification, can you explain why you are using [Program] instead of [refine]? Your problem is a non-issue with [refine], since you simply run [refine implementation; your_default_tactic] in the proof script for the function you're writing.
