Ref return values are a very new feature in D2.  I suspect its just a
bug that they don't work on inner functions yet.

 No, a report is probably needed.  There are lots of bugs with the new
 const and ref features in D2.  Many have been reported, but there are
 still many more to be discovered.  Returning refs in particular is
 very new, so I would expect bugs a plenty with that, though I think
 few have been reported so far.  I don't keep up with the bugs
 newsgroup these days, though.  Certainly try to search for it in the
 bug db before filing a new report, though.  D's bugzilla is here:
