I looked a bit and could not find the rule except in the paper
"wxHaskell – A portable and concise GUI library for Haskell" (see 
http://legacy.cs.uu.nl/daan/pubs.html#wxhaskell ), which I guess is the
one you refers to.

It would be good if we added the use-only-once rule somewhere. Do you
have a suggestion? Can you name a place where would you would have found
it?
