I intuited that that's what the problem was.
Thanks,

ghci does not know what type of enum you want to create from the number 2.
Try: toEnum 2 :: DayOfWeek
That said, I would expect "toEnum 2" to give an error like: 'Ambiguous
type variable `a'....'. So I am not sure why your error message says:
'** Exception: Prelude.Enum.().toEnum: bad argument'
