Why does C++ not have reflection?
... problems with reflection in C++.
It's a lot of work to add, and the C++ committee is fairly conservative, and don't spend time on radical new features unless they're sure it'll pay off. (A suggestion for adding a module system similar to .NET assemblies has been made, and while I think there's...
Fundamental difference between Hashing and Encryption algorithms
...f (MD5 does this 64 times for each 512bit chunk of data). It then somehow combines the resultant states from all these iterations back together to form the resultant hash.
Now, if you wanted to decode the hash, you'd first need to figure out how to split the given hash into its iterated states (1 ...

How can you do anything useful without mutable state?
...ts, and move the imperative state to the stack. A for-loop, for example, becomes recursion:
// Imperative
let printTo x =
for a in 1 .. x do
printfn "%i" a
// Recursive
let printTo x =
let rec loop a = if a <= x then printfn "%i" a; loop (a + 1)
loop 1
