FiniteMap has been superceded by Data.Map, this is probably what you want to use (or Data.IntMap if your keys are Int). -- Jedaï

Hello,

I tried to load FiniteMap module in ghci and encountered an error message like the following:

Prelude> import FiniteMap Could not find module `FiniteMap': it is a member of package ghc-6.8.2, which is hidden

The error message says that it is hidden. How can I use the FiniteMap?

Regards, Kwang Yul Seo

As Chaddai said, it's obsolete and superceded by Data.Map and Data.IntMap. But the names and types of some functions have been changed, if you don't want to change the tutorial code so that it works with the new modules, you can ghc-pkg expose ghc-6.8.2 then work with FiniteMap and afterwards ghc-pkg hide ghc-6.8.2
