Constants in V

const (
	pi    = 3.14
	world = '世界'
)

println(pi)
println(world)

// Constants are declared with const. They can only be defined at the module level (outside of functions).
// Constant values can never be changed.
// V constants are more flexible than in most languages. You can assign more complex values:
struct Color {
	r int
	g int
	b int
}

pub fn (c Color) str() string { return '{$c.r, $c.g, $c.b}' }

fn rgb(r, g, b int) Color { return Color{r: r, g: g, b: b} }

const (
	numbers = [1, 2, 3]

	red  = Color{r: 255, g: 0, b: 0}
	blue = rgb(0, 0, 255)
)

println(numbers)
println(red)
println(blue)
