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...
Why does one use dependency injection?

std::string s1 = "123";
std::string s2 = "456";
std::string s3_copy = s1 + s2;
const std::string& s3_reference = s1 + s2;
In this example s3_copy copies the temporary object that is a result of the concatenation. Whereas s3_reference in...

Just for completeness: If you'd actually want to calculate Fibonacci numbers using this recursive approach here is an opti...
What are some (concrete) use-cases for metaclasses?

With only a couple functions I found that I was able to increment the figure count, call draw manually, etc, but I needed to do these before and after every plotting call.
