Let

The let keyword declares variables in GLuaX.

• Variables declared with let can be changed after assignment.
• You must provide an initial value for each variable.

Syntax

let name: Type = value;
let a, b: number = 1, 2;
let x = 42;

• Multiple variables can be declared at once, separated by commas.
• Type annotations (: Type) are optional for local variables, but required for top-level (item) variables.
• Each variable must be initialized at declaration.

Examples

let x = 10;
let y: string = "hello";
let a, b: number = 1, 2;

Scope

• Item let: Declared at the top level of a file (outside any function or block). These are global to the module.
• Non-item let: Declared inside functions or blocks. These are local to their scope.

let GLOBAL: number = 123;

func main() {
    let local = 5;
    print(GLOBAL, local);
}

Notes:

• pub can only be used with top-level let.
• Type inference is only allowed for local (non-item) variables.
