Path

Start with examples.

Then move into the spec, release notes, and error codes.

Small programs that match the published language surface.

The spec, types, declarations, expressions, and runtime behaviour.

Version changes, milestones, and the current stable surface.

Examples

Small examples aligned with the reference.

fun main() {
    println("hello, Metel");
}

struct Point {
    x: Float,
    y: Float,
}

match value {
    Perhaps::Some { value } => value,
    Perhaps::None => 0,
}

Reference
