++对于并行计算简直就是噩梦，Java虽然对并行的支持要好很多但其实并没有本质区别，同时
performance又要打很多折扣（现在大部分还是用Java的middleware来调用C++ library
）。Functional programming 在消除了side effects后，debugging要容易很多，
parallelization则是水到渠成。
摩尔定律已经不再使用，计算机硬件再也不可能像过去30年的速度发展下去，并行计算
将是今后的趋势。有兴趣的可以看看下面的文章

不过不是很明白为什么functional programming会很适合做parallel programming
我觉得虽然C++易用性差，现在并行计算还是不少用C/C++的吧 |

right now.
Nobody knows what the world will be 5 years from now, but it will surely be
very different from today.

There are things that you can do better in functional programming. But most
importantly, there are things you CANNOT do in functionl programming. i.e.
you can't change the value of a variable once it is defined (therefore you
cannot iterate over a loop) This force you to think differently.
Functional programming was once for academic research but it has already
sparked a lot of interest in finance and I can only see this grow in the
future.

发帖数: 3964 | 8 一直觉得搞不明白C++的人才会对其他语言很感兴趣。学不会C++的人（换句话说哪一门
语言也学不通）是少数，他们把自己的问题归咎于C++哲学理念和自己的生辰八字，转
而寄希望于少有人用的一些新品种，站在更高的层次掩耳盗铃。
80%的日常应用scripting应该就能对付了。如果你不幸必须跟踪调试剩下一小部分要求
高的底层程序，我相信任何functional语言不会跟C++有本质区别。至于并行，且不论C
++是否真的不便并行，有什么应用必须用到并行计算么？distributed computing不算
。 |
