发帖数: 1252 | 2 Where did you see the "sudden" interests?
FP was introduced to mainstream languages like C++ since more than
10 years ago, not to mention scripting languages like python and
javascript. It's working but is not the silver bullet.
If you mean CMU's recent drop of OO courses, they actually plan to
teach both imperative and functional, with an emphasis on invariants
and pre/postconditions for verification. BTW, MIT replaced scheme
with python a few years ago.

Actually the question could be rephrased as what good
does functional bring to parallel processing. I can
see the links from functional->recursion->parallel,
but not totally convinced.

approach. I think that's why language like Scala is gaining
ground.

Actually what do you think about Scala?
Will it be the next JAVA or next C++?
Or, for a freshman in CS, should the first
programming language class offered in Scala
(and forget about JAVA and C++)?

发帖数: 34805 | 9 Scala is too complex a language to be the first programming language.
Java is a fine language for teaching OOP.

发帖数: 1970 | 10 scala对新生来说太复杂了，比c++还繁杂，并不是太看好他。得有个好的编程规范，限
制使用一些东西，否则写的东西很容易别人看不懂。

发帖数: 5159 | 14 In my learning process of Ocaml, I found it could prevent potential bugs, e.
g., mixed up array indices and array values, and doing it much better than a
compiler like g++.
Meanwhile, it develops faster in some application. Writing a qsort in ocaml
is much faster than doing it in C++.

就象你说的同样适用于dynamic programming language。
很大一个原因是机器能处理得过来了。 而且有成功的例子了。dynamic 有ruby。还有
重新火起来的javascript。如果没说错的话。
