This function accepts two passed parameters, then prints the first, and 
reads and prints one line from the second.  Obviously, to work the first 
must be printable, and the second must provide a readline method.

*IF* you believe that the names selected accurately represent the intent 
of the function, you may come to the type of conclusions you reach below.
