Thanks!  The problems have indeed been fixed.

Thanks.  It seems that I have written testcases for a while :-(

Is this supposed to remain so, or will there be some effort to arrange
that functions with named return values become inlinable?  If they
will remain uninlinable, I'll post a patch to the docs to state this.
Maybe we should even deprecate named return values, now that we have
inlining of trees, which I believe accomplishes a similar degree of
optimization.
