What is the rationale behind the sudden interest in
Functional Languages? It had been around for so long,
30 years or so, and there is no theory/technique
breakthrough happening right now.

The example is from Wiley MODULE 11, page 360:
Units of one bond and one warrant (to buy 10 shares of stock at $50/share)
are issued for $1030. Therafter, warrants trade at $40 and the bonds at $960
. The ralative market value of the warrants is 4% and the relative market
value of the bonds is 96%. Thus, $41.20 (.4X$1030) of the issue price is
assigned to the warrants.
DR Cash 1030
DR Bond discount 11.20
CR Bonds payable 1000
CR Paid in capital-stock warrants 41.20
If one warrant

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.

I don't have the textbook with me now but think that Becker mentions this
briefly in Chapter 7 (Stockholder's Equity, and it should be on the upper
portion of page next to Subscription， or the page after). I recall that
because I noticed that Becker uses the term (warrant) in there and thus went
back to Chapter 5 of Bond and compared them.
Anyway, they don't provide too much deails either, but my understanding is $
54 of stock price is a "fact", and warrant is supposed to be equivalent to
stock

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.

Thanks!
So, when exercising the warrants, can I make the JE like this?
DR Cash 50
DR APIC-warrants 4
CR Common stock parX1
CR Paid-in excess (plug)

Pure functions have no internal state, which makes it
easier to parallelize.

Actor model is simpler than threading concurrency in an asynchronous
approach. I think that's why language like Scala is gaining
ground.

scala 2.9还新加了parallel collection.

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++)?

Scala is too complex a language to be the first programming language.
Java is a fine language for teaching OOP.

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。

就是一群外行看到了一个他们不懂的东西觉得很兴奋。等弄懂了以后就会发现白欢喜了
一场，问题还是没解决。
haskell发明了一个IO monad把现实世界隔离到了程序外面, 然后宣布: 我们在(现实世
界以外)实现了纯函数式编程. 真是迂腐得很.

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++.

you don't need to write a qsort in C++.

听微软presentation说是Multi－core。
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。
