Memoization in Haskell?
... f does what you mean for small values of f by calling, for example: fix f 123 = 144
We could memoize this by defining:
f_list :: [Int]
f_list = map (f faster_f) [0..]
faster_f :: Int -> Int
faster_f n = f_list !! n
That performs passably well, and replaces what was going to take O(n^3) time...

... products and then provide a link on each product to maybe a /Product/Edit/123 action method to edit each one on it's own form. I think you can become undone trying to do too much on one page in MVC.

What does curly brackets in the `var { … } = …` statements do?
...h more succinct.
For example:
var ascii = {
a: 97,
b: 98,
c: 99
};
var {a, b, c} = ascii;
The above code is equivalent to:
var ascii = {
a: 97,
b: 98,
c: 99
};
var a = ascii.a;
var b = ascii.b;
var c = ascii.c;
Similarly for arrays:
var ascii = [97, 98, 99];
var [a...
