Are you tired of all of that modules, processes and functions nonsense? Do you want to just use classes, objects and methods? If so, use OOP [1] library in Elixir [2]!
[1] Actually, according to Alan Key, the inventor of OOP, “objects” is the lesser idea; the big idea is “messaging”. In that sense, I can’t agree more with Joe Armstrong’s quote that Erlang is “possibly the only object-oriented language”.
[2] Please don’t. You’ve been warned.
import OOP
class Person do
var :name
def say_hello_to(who) do
what = "Hello #{who.name}"
IO.puts("#{this.name}: #{what}")
end
end
joe = Person.new(name: "Joe")
mike = Person.new(name: "Mike")
robert = Person.new(name: "Robert")
joe.say_hello_to(mike) # Joe: Hello Mike
mike.say_hello_to(joe) # Mike: Hello Joe
mike.say_hello_to(robert) # Mike: Hello Robert
robert.say_hello_to(mike) # Robert: Hello Mike
joe.set_name("Hipster Joe")
joe.name # => Hipster Joe

The ability to troll other people is unlimited!
I love it.

This is absolutely amazing. The next step is a Ruby cross-compiler!
All joking aside, my mind is blown by how much you can do with Elixir’s metaprogramming features. Thank you for sharing!

Or @wojtekmach you could bite the bullet and actually learn FP on its own terms.
To abuse an analogy, stop trying to ride two horses at once. Eventually you’ll fall off and they’ll trample you.

Hey Onorio, not sure if you’re meta-trolling but this library is supposed to be a joke
Onor.io
Ah–ok, then disregard my reply. Didn’t realize you were joking.

How do I implement static methods using this library? Or should I create a Singleton instead? Or maybe use some sort of dependency injection?
wojtekmach
@pablo static methods are not supported yet but PRs are welcome

Jokes aside , Combining OOP and Functional programming has advantages in a select few cases.
I had a lot of fun with swift in that regard. (you could possibly do it in JS as well , but no … just no )

Actually I would not consider this idea as a joke, even if the above implementation is one: have You ever read The Art of the Metaobject Protocol?

@bsmr you have quite successful OO with classes or prototypes implementations in languages that do not support it out there. This is simply a matter of syntatic sugar and mechanisms built into the language, that make it easier.
GObject in C is good example, it is heavily used in Linux world.
Open question remains if binding data with functions together is such a great idea. Personally I think it impedes ability to use functional programming style. It also encourages you to create functions that have side-effects, rather than transforming the data in visible, clear manner. Not to mention that majority of OO implementations are also promoting mutable data structures.
