Hello again.

I finally got it myself. It was just a matter of parentheses:

See http://hpaste.org/fastcgi/hpaste.fcgi/view?id=3229 for the corrected version.
Looks like what I was trying to do is not expressable via just an arrow, one needs a function mapping the input arrow to a new one.

I'm gonna make a big "WATCH YOUR PARENTHESES!" poster... Yeah, with some arrows on it...

Thanks for reading, anyway.
