Yet this resource seems a little outdated:
http://www.haskell.org/haskellwiki/Performance/Strings does not speak about Text
http://www.haskell.org/haskellwiki/Performance/Arrays about Vector
And what's the status of the Streams IO approach detailed in http://www.haskell.org/haskellwiki/Performance/IO ? Has it evolved into enumerators/conduits, or was that an unrelated approach?
