How can I extend this version to multiple loggers, like the article does? Do I need to write in my application code:

  writeStringToFileAndWrappedSocket(w: WrappedSocket, f:File, s:String) = writeStringToFile(f,s) and writeStringToWrappedSocket(w,s)

If this is written in the library, that is 2^n combinations of file output functions - even worse than the n*m the article complains about.
