Does functional programming replace GoF design patterns?
...n patterns
found available to every other OOP
language. In fact, right now I use F#
and OCaml everyday, and there are no

Java.
Perhaps because you're still thinking imperatively? ...
Why can't yield return appear inside a try block with a catch?
...iables in the generated type, so you can freely move code to new methods

Console.WriteLine("a");

> s.slice(2, s.length-2).split("','");
["first string", "more", "even more"]
To extract a s...
