Doesn't the snippet above hide the errors and warnings (since I do not see any code to print them)? Does not seem very ergonimic to me.

  No it does not, in fact; errors or warnings will pop up as an unhandled exception and print: - command actually executed, - snippet of stdout - and snippet of stderr. They can be handled using standard exception techniques.

    Isn't that only for failed commands? so if command succeeds with warnings, or if if fails, but the retries and passed, ghen you get no output.

      The exception is raised if the command returns a non-zero error code. If it returns a zero error code then the return value of, say, compose.up() contains the command's stdout. In addition stdout can be redirected to a file, or to another command, or to a callable, ­— which will be called for chunks of stdout while the command is in operation.
