// Demonstrating type classes (traits) in Lux

// Expected output:
// RGB color: rgb(255,128,0)
// Red color: red
// Green color: green

// Define a simple Printable trait

// Implement Printable
impl Printable for Int {
    fn format(value: Int): String = "Number: " + toString(value)

// A Color type with pattern matching

    | Blue
    | RGB(Int, Int, Int)

// Test

// Print results
