That is a good suggestion. Also, MIT Scheme understands a few escaped
character sequences within strings, such as \\, \", \n, \t, \f, and octal
escape sequences (only the first two are part of the Scheme standard,
though). For example, you can include \n in strings sent to display:

    (display "Stack underflow.\n")
