Hi Dan.  It's good to hear you're working on it again.  Is this post-thesis? :-)

There are probably several passes that reverse the order of function arguments.
I just checked and flattening is one for sure, but there are probably others.
It seems like an easier solution would be to look for the rhandle argument in
any position.  Is there a reason that won't work?
