What is the point of function pointers?
I have trouble seeing the utility of function pointers. I guess it may be useful in some cases (they exist, after all), but I can't think of a case where it's better or unavoidable to use a function pointer.

What's the absurd function in Data.Void useful for?
...pe is involved in the return type of a function.
absurd arises when we're converting between these two representations.
For example, callcc :: ((a -> m b) -> m a) -> m a uses (implicit) forall b. It could be as well of type ((a -> m Void) -> m a) -> m a, because a call to the c...

What is the difference between procedural programming and functional programming? [closed]
...eries of sequential steps. (There's a way of transforming sequential logic into functional logic called continuation passing style.)
As a consequence, a purely functional program always yields the same value for an input, and the order of evaluation is not well-defined; which means that uncertain v...

Why does SIGPIPE exist?
...lue's in the fact that SIGPIPE kills you by default - it's not designed to interrupt a system call, it's designed to terminate your program! If you're able to handle the signal in a signal handler, you could just as well handle the return code of write.
