Enforcing invariants in Scala datatypes

Scala provides many tools to help us build programs with less runtime errors. Instead of relying on nulls, the recommended practice is to use the Option type. Instead of throwing exceptions, Try and Either types are used for representing potential error scenarios. What’s common with these features is that they’re used for capturing runtime features in the type system, thus lifting the runtime scenario handling to the compilation phase: your program doesn’t compile until you’ve explicitly handled nulls, exceptions, and other runtime features in your code.

Most of what's written in this article is deliberately biased and wrong. It is yet another in the stream of Scala-hating posts that people. I analyze the article below:

1. TIOBE index is a metric based on search engine ranking policies and can be intentionally or unintentionally gamed.

   https://blog.timbunce.org/2009/05/17/tiobe-index-is-being-gamed/

On these rankings, Scala is quite high:

Hi all!

After a very lengthy period of development and testing, FS2 (formerly scalaz-stream) version 0.9 is finally out! Here's how to get it.

For this release, the library has undergone a major redesign. Check out the migration guide for more info, and also the shiny new user guide. Going forward, we expect the API of the library will be quite stable and hope it becomes one of the bedrock libraries of the Scala ecosystem. The 0.9 series has already seen production use as well as a huge amount of testing during the development process; we feel very good about recommending people upgrade.

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

Recursion and Trampolines in Scala

Recursion is beautiful. As an example, let's consider this perfectly acceptable example of defining the functions even and odd in Scala, whose semantics you can guess:

def even(i: Int): Boolean = i match {
  case 0 => true
  case _ => odd(i - 1)
}

def odd(i: Int): Boolean = i match {
