Re: [Haskell-cafe] Data.ByteString vs Data.ByteString.Lazy vs Data.ByteString.Char8

I think I am getting a namespace collition between

Data.ByteString.Lazy.Char8.ByteString

Data.ByteString.Lazy.Internal.ByteString ....

You rarely need to import 'Internal' directly.

here is the error message ....

Couldn't match expected type `B.ByteString' against inferred type `bytestring-0.9.0.1:Data.ByteString.Lazy.Internal.ByteString'

Are you sure this is not just a versioning problem? I.e. that some library is built against bytestring-0.X.Y, but your current import is bytestring-0.A.B, but your program expects these to be the same? (And they probably are, but the compiler can't really tell). -k -- If I haven't seen further, it is by standing in the footprints of giants
