Thanks for the tip, I'll check it out.

  RP> Yes, that's a lot of backslashes!

Oh you're right! I had removed two backslashes because it did not work
at first, but trying again now it seems all fine. Maybe that's because
I was using the 0.3.0 release, while I compiled the hg head now.

Completely true, I'll definitely make it uglier as I move on solving
issues. I was just starting to play with simple cases to experiment
with lenses.
