[Haskell-cafe] Data.ByteString.Lazy.ByteString vs Data.ByteString.Lazy.Internal.ByteString

Hi, I noticed that even though I declare the type of a function in my code as Data.ByteString.Lazy.ByteString ... when I check it out in ghci using :t, it shows this - Data.ByteString.Lazy.Internal.ByteString Is this expected? Regards, Kashyap
