Blocks

A block is a collection of statements ran sequentially. Blocks come in 3 types:

• Multi statement block
• Single statement block
• Explicit scope

Multi Statement Block

Multiple statements can go inside of this block. You’ll find most of these in things like if blocks, functions, loops, namespaces, etc. Multi statement blocks are made with braces {...}. Each block is scoped so all variables defined can only be accessed inside it. Inside the braces write all the code you want executed.

if x > 10 {
    println("Hello")
    println("World")
}

Single Statement Block

Single statements can go inside of this block. Write a fat arrow => followed by the code or a value. Single statement blocks also run an out and are useful for shorthand inline code.

if x > 10 => println("Yes")

let user = "admin"
let permissions = if user == "admin" => "admin"
                  else => "guest"

Explicit Scope

In a few cases you may need a separate scope for some things. (Like shadowing a variable). These function just like Multi Statement Blocks. Manually create an explicit scope using @ { ... }

let x = 10

@ {
    let x = 123
    println(x)  # prints 123
}

println(x)      # prints 10
