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>
I see the same problem with GHC 7.0.2, time-1.2.0.3. Does it work if you use it in a Haskell source file, instead of GHCi? Thanks, Antoine
The documentation says that Day has an instance for Read. Regards, Kashyap _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
