Re: [Haskell-cafe] why does Data.Text.Lazy.IO.readFile return the internal type Data.Text.Lazy.Internal.Text, when Data.Text.IO.readFile returns plain IO Data.Text.Text?

Data.Text.Lazy.Internal.Text = Data.Text.Lazy.Text Data.Text.Internal.Text = Data.Text.Text You can use fromChunks/toChunks from Data.Text.Lazy to break it up into strict Text fragments. The lazy version returns a Lazy Text value, which is isomorphic to [Data.Text.Text]. The strict version just returns a single strict Text value.

but

*Main> :t Data.Text.Lazy.IO.readFile Data.Text.Lazy.IO.readFile :: FilePath -> IO text-0.7.1.0:Data.Text.Lazy.Internal.Text

why does the lazy version use the internal type, whereas the strict version of Text IO just using plain Data.Text type? and how can I get from internal type to regular type when using Data.Text?

also the internal type doesn't appear to be reflected in the haddock:

http://hackage.haskell.org/packages/archive/text/0.7.1.0/doc/html/Data-Text-...

ghc-pkg list | grep -i text text-0.7.1.0
