Ok good. Like I said you are a very smart kid, and drugs would only ruin your hopes, dreams, and your desire to be a good, honest person. It will kill your zest for life! You really should remove that Hansen song from your signature though, and stop listenting to that crap. That will also ruin your life!:laugh::laugh::laugh::cool:

Not very different than prolog or scheme (my favorite language). Prolog:
sum([X | Y], Z) :- sum(Y, A), Z is A + X.
sum([], 0).Scheme:
(define sum (lambda (x)
(if (null? x) 0 (+ (car x) (sum (cdr x))))))Co-Author ASP.NET AJAX in Action
Scheme and its never ending parens reminds me of this XKCD on Lisp[^]. :)

I've been studying F# a lot recently and find it really mind-bending. Tomas Petricek, a fellow CPian, let me sneak preview his series of F# articles and they are very good. I took one of his examples and modified it a bit. The following code displays "sum = 6", but how that happens is other-worldly...check it out:
#light
let rec sum nums =
match nums with
| head::tail -> head + sum(tail)
| [] -> 0
printf "sum = %i" (sum [1; 2; 3])Weird, eh? F# is coooool. :cool:

Argh! Don't say that!! I, too, feel that I "must remain" pidgeon-holed into WPF. But I don't want to feel trapped like that. I am a bit tired of WPF at the moment, considering that I've studied nothing else for the past two years! Plus, part of my agenda[^] is to see if/how F# and WPF can work together.

Oh...I remember this. In my Programming Languages class when we did ML....*shivers* Right when I saw "head::tail" and the recursive call. I would like to see a whole application written in this, though. - Keith

Nah, I like Maynard. I admire him perhaps more than anybody else. Not that I would ever tell anyone such a thing... :doh:

Wouldnt that just destructure your input list into 'head' and 'tail' variable? Perhaps the '::' has special meaning?
Keep in mind, I've only been studying F# for a few days now. But, my current understanding is that F# uses the x::y syntax for dealing with its "list" type. You can create a list, or pull one apart, with that :: operator. AFAIK, writing "head::tail" (or foo::goo) is a way of saying "Give me the first cell in the list, and then also give me the remainder of the list."

Ahh so it similar to to Scheme/Lisp's

Hahaha. Yeah right. I get the feeling that F# isn't going to become a "mainstream" .NET language anytime soon. It's out there: far, far out there. It has virtues different from clarity and code maintainability. I'm just a newbie so don't quote me, but supposedly using F# as a functional programming language allows you to more easily write code which can be parallelized across multiple processors or cores. I'm interested to see how to do that, because I think that's an important aspect of modern software design.
:josh: My WPF Blog[^] Without a strive for perfection I would be terribly bored.
It's for problems where you indicate what you want performed on every member of a list (map) or how you aggregate the contents of a list (reduce). In theory, because each of the operations is atomic (independent of the other items), in the case of the map operation, or the result of reducing the whole list is the same as reducing distinct subparts of the list then reducing the results of those suboperations, you can farm out subparts of the list to other cores to execute in parallel. Because it's implicit, the environment can scale the algorithm appropriately to the number of installed cores. Still, it's not much that a parallel foreach couldn't do. It's just we're not used to writing our programs as such discrete blobs of functionality, effectively putting half your program out-of-line. And I'm not sure that many of the programs we regularly use would benefit - your data set would have to be pretty big to overcome the cost of the inter-thread procedure calling required to get another core working on part of the problem. I'm not totally sure the MHz myth is as over as it seemed a few years ago. The 45nm generation with high-k dielectric looks like it may have solved or at least alleviated the leakage problems that caused such trouble with overheating when trying to ramp up the clock speeds. The Core 2 Duo E8500 is supposed to clock at 3.16GHz while keeping a Thermal Design Power of 65W (source[^]).
