This is a programming error to do so: if you aren't sure that the input string is newline-free, do not rely on the   Z instance.HWhen debugging, it might be useful to look for implicit invocations of  for Z: Q>>> sh (do { line <- "Hello\nWorld"; echo line }) *** Exception: NewlineForbiddenIn the above example, echo expects its argument to be a Z, thus line :: Z.
