Effectful.FileSystem.IO.ByteString.Lazy

Lifted Data.ByteString.Lazy.Char8. Like the original module, you probably want to import this module qualified to avoid name clashes with the functions provided by Prelude, e.g.:

import Data.ByteString.Lazy (ByteString)
import Data.ByteString.Lazy.Char8 qualified as LBS8
import Effectful.FileSystem.IO.ByteString.Lazy qualified as ELBS
