[Haskell-beginners] consing an element to a list inside a file

[kane96 at gmx.de]

ok, looks much easier and works :)

But what are now the correct signatures for the function? Normally the "one and only" function should be: readCal :: IO Calendar
My function are: readCal = readCal2 datelist
and: readCal2 datelist = do... which returns the Calendar (the list of dates)
