Pattern Matching

Use match expressions for clean conditional logic.

The `match` expression works like a switch statement, but it's an expression — it returns a value. Use `=>` to separate patterns from results.

let describe = n -> match n
	0 => "zero"
	1 => "one"
	_ => "many"

for x in [0, 1, 5]
	describe x | print

Sloplang has a powerful **cond-style match** — a `match` with no value that checks conditions top to bottom. This is perfect for FizzBuzz-style logic.

for x in 1..=20
	match
		x % 15 == 0 => "FizzBuzz"
		x % 3 == 0 => "Fizz"
		x % 5 == 0 => "Buzz"
		_ => x
	| print

Match works with enums and destructuring, letting you pull data out of tagged values.

enum Shape {
	Circle { radius },
	Rect { w, h },
}

let area = s -> match s
	Shape::Circle { radius } => 3 * radius * radius
	Shape::Rect { w, h } => w * h

let shapes = [
	Shape::Circle { radius: 5 },
	Shape::Rect { w: 3, h: 4 },
]

shapes | map area | print
