International Conference on Functional Programming 2006大赛结果：
第三名Team: Can't Spell Awesome Without ASM, from Google，使用汇编
第二名Team kuma， from Japan，使用D语言
第一名Team Smartass， from Google，使用Haskell，并辅以C++/Python/2D语言。

Haskell连续三年蝉联第一！

今年的题目背景是虚拟的‘计算考古学’，要求实现一个指定规范的虚拟机以执行‘古代文明代码’完成各种任务。

2D语言特别介绍（from wikipedia）
2d is a programming language that appeared in the 2006 ICFP programming contest. Programs written in this language are drawn out as ASCII flowcharts using boxes and arrows, as shown in the following example.

,....................................,
:p |  *=================*            :
---#->!send[(W,S),(W,E)]!+           :
:  v  *=================*v           :
:*=============*| *===========*      :
:!case N of S,E!#>!send[(N,E)]!-------
:*=============*v *===========*      :
:      |   *=====*  *===============*:
:      +-->!use p!->!send[(Inl W,E)]!-
:          *=====*  *===============*:
,....................................,

While on the surface the language appears much like a description of a printed circuit board, it differs from physical circuits in many significant ways. In the 2d language, arbitrarily large and complex values may be passed along a wire. In addition, 2d boxes may make recursive references with the use keyword.

Participants in the contest were asked to write several programs in this language, including a 1-dimensional ray tracer. Programs were evaluated both on the correctness of their output and on their size: programs with smaller areas were worth more points.
