I'm not quite following what you're doing here, maybe if you have a
small snippet of code that demonstrates the problem that would help?
(But just to warn you, if the problem isn't stopping you from getting
work done, then answer might just be "wait for mred v2" -- Matthew is
redoing all of that code is a better way.)

Thanks for the kind words. Things like this are what keep us going.
