I'm probably doing something wrong but this example doesn't compile for
me under ghc 6.10.1
(http://www.haskell.org/ghc/docs/latest/html/libraries/base/Control-Exception.html#4):
catch (openFile f ReadMode)
(\e - hPutStr stderr (Couldn't open ++f++: ++ show e))
Run.hs:77:24:
CE.catch :: (CE.Exception e) = IO a - (e - IO a) - IO a
foo d = CE.catch (openFile d ReadMode return ())
(\e - hPutStr stderr (Couldn't open ++ d ++: ++ show e))
btw, if your handler cannot return the same type as your action, is this
the right place to catch the

That was an example, the real code looks something like this:
do d - getCurrentDirectory
t - getCurrentTime
let u = asn1c. ++ show (utctDay
