Oh, I didn't know this option, good idea, thanks :D

You're right, though I prefer to use "bar" to show there is no relation
between
the package name and its module.
I added "[PATCH]" to the subject to get others look at this message. I
plan to
push it in a few days unless it gets more comments. If an experienced
schemer
could look at that, I'm sure the coding style could be improved a lot ;)
