[Haskell-cafe] Data.Time.Calendar.Day does not seem to have an instance for Read

Hi, I was wondering if this is a defect - Prelude> import Data.Time.Calendar Prelude Data.Time.Calendar> read "2011-10-10" :: Day <interactive>:1:1: No instance for (Read Day) arising from a use of `read' Possible fix: add an instance declaration for (Read Day) In the expression: read "2011-10-10" :: Day In an equation for `it': it = read "2011-10-10" :: Day Prelude Data.Time.Calendar> The documentation says that Day has an instance for Read.
