libghc-resourcet-prof 1.2.2-1build1 (armhf binary) in ubuntu groovy

 Control.Monad.Trans.Resource allocates resources which are guaranteed
 to be released. One point to note: all register cleanup actions live
 in the IO monad, not the main monad. This allows both more efficient
 code, and for monads to be transformed.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
