I could of course write a genAlloca if the MonadIO class was extended with a bracket method:
Besides extending MonadIO with bracket, maybe it's also useful to extend it with:
catch :: Exception e => m a -> (e -> m a) -> m a
You might want this library: http://hackage.haskell.org/packages/archive/MonadCatchIO-transformers/0. 0.1.0/doc/html/Control-Monad-CatchIO.html There's also an mtl version; not sure which is to be prefered.
