docs: Adds an output stream; this method allows to specify whether the
  stream should be closed when the T stream is closed. If you want to
  use standard output as one of the streams in the T, this is the method
  to use, passing in {@code false} for parameter {@code autoclose}.
  
  @param stream
  the stream to add to the T.
  @param autoclose
  whether the stream should be closed automatically when the T is closed.
  @return
  the object itself, for method chaining.
