Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
...gen , it wasn't meant to be insulting (since I didn't actually ascribe the label to anyone specific), it was just an indication that pow doesn't really require much skill. Certainly I'd rather have the standard provide something which would require a lot of skill, and result in far more wasted minut...
How exactly does the callstack work?
...tart of a function which subtracts from SP the value of a forward-declared label. Within the function, the compiler can at each point in the code keep track of how many bytes worth of locals are still in scope, and also track the maximum number of bytes worth of locals that are ever in scope. At t...

What does the `forall` keyword in Haskell/GHC do?
...nswer is that we can!
A function that puts type variables together with a label and returns a new type is a type constructor, which you could write something like this:
