Since I want to use the arrow notation, I had a close look at the following description, taken from http://www.haskell.org/ghc/docs/latest/html/users_guide/arrow-notation.html [example in 7.7.1. do-notation for commands]
The arrow I want to create is one to track down dependencies. This doesn't seem to work with arrow notation, because in the example above
g -< 2*y
isn't used in the following statements but is bound to the next arrow:
No, the output of g is discarded by the arr snd. For another approach to tracking dependencies, see slides 23-26 of http://www.soi.city.ac.uk/~ross/talks/fop.4.ps.gz
