Well, the typical program which prints "Hello World!" is difficult for
_purely_ functional languages since IO is a side effect.  Of course, a
language which could not interface with the outside world would be
deemed to be purely academical.  Maybe in the functional world the
equivalent example should be "2 * 4"? :-)
