Actually, something like

do ...
    if <- checkCondition
      then doReportSuccess
      else doReportFailure

as well as

do ...
    case <- generateResult of
      Nothing -> ...
      Just r -> ...

instead of

do ...
    b <- checkCondition
    if b ...

and

do ...
    r <- generateResult
    case r of ...

would be very nice.
