Language features

Immutable variables

let Name = "kenny"
Name = "def" // Error!

Tuples

let Person = (123, "Lukasz")

Atoms

let Person = (person, 123, "Lukasz")
let Place = (place, 222, "Krakow")

Pattern matching

let Person = (person, 123, "Lukasz")

case Person of
    (person, Id, Name) -> {
        printf("Person: %s", Name)
    }
    (place, Id, Name) -> {
        printf("Place: %s", Name)
    }
end

First class functions

let f = fn(x) -> {
    return x + 5
}

let result = f(10)

Lightweight processes

process User {
    let name = "lukasz"
    
    cast changeName(newName) {
        return User{
            name: newName
        }
    }
    
    call getName() {
        return this.name 
    }
}

let u = spawn User()

u.changeName("newName")
