[Haskell-cafe] list utilities -- shouldn't these be in the hierarchical libs somewhere?

I found http://haskell.cs.yale.edu/haskell-report/List.html had many useful "one off" type list functions such as "subsequences" and "permutations" which are nowhere to be found in hoogle, Data.List, or the haskell hierarchical libs Shouldn't these be included somewhere? thomas. --- This e-mail may contain confidential and/or privileged information.
