The dollar thing is for return values.  The Guile manual uses the arrow,
but that would be incorrect in the above example as =E2=80=9CHello world=E2=
=80=9D is not
returned by =E2=80=9Cdisplay=E2=80=9D =E2=80=94 it is merely a side effect.=
  In the Guile manual
this would be indicated by =E2=80=9C=E2=8A=A3=E2=80=9D.
