Hi Tomek!
Hi!
Have you considered changing the statements to have type 'ReaderT Database IO ()'? Then (>>) actually does what you want.
I tried it and it made the code simpler, more readable and of course more immune to this type of bugs. Thanks!
I use the same idea in Hope (http://hope.bringert.net/), with a newtype DatabaseT, and a typeclass MonadDatabase, and lifted versions of the HaskellDB database operations. The code is in the first part of this module: http://www.cs.chalmers.se/~bringert/darcs/hope/Hope/ DatabaseT.hs Perhaps this should be added to HaskellDB? /Björn
