// Test: [expand] annotation for template-based code generation
// This tests the simplest case: an event with [expand] that uses a template
// to generate inline Zig code without needing a proc.

    @import("std").debug.print("value: {d}\n", .{ {{ value }} });

// Event with [norun|expand] - implementation comes from template
// [norun] = not emitted anywhere
// [expand] = processed by transform_pass_runner via template lookup
[norun|expand]pub event debug-print { value: Expression }

// Use it - note the ~ prefix to make it a Koru flow!
