[Haskell-cafe] Dynamic loading of module

After reinstalling HP 2011.2.0.1 and (re)wiping out user package directory,
things are in better shape and I can now compile the faulty module. I am
well aware I did something wrong at some point in time but I am not really
sure of what happened. I suspect things went wrong when I tried to install a
recent version of snap framework : I vaguely recall having to upgrade some
"core" modules to make cabal happy which obviously was not a good thing.
Maybe this already exists but it would good to have some "session-like"
feature in cabal that would allow fiddling with the configuration and give
the user the ability to rollback what she did. Not sure this would be to
easy to implement though...
Thanks again for your help.
Best regards,
Arnaud
