011 print ln continuation ordering

// BUG: print.ln inline code ordering in nested for loop with void events
//
// REPRODUCTION: Matches the nbody pattern exactly:
// - for loop with void events in | each |
// - branched event in | done |
// - print.ln using the branch binding

const std = @import("std");

~import "$std/control"
~import "$std/io"

// Void event (like advance_velocities)
~event step_one {}

~proc step_one {}

// Another void event (like advance_positions)
~event step_two {}

~proc step_two {}

// Branched event (like calculate_energy)
~event get_result {}
| value i32

~proc get_result {
    return .{ .value = 42 };
}

// Print event with a result (like print_energy)
~event print_value { v: i32 }

~proc print_value {
    std.debug.print("{d}\n", .{v});
}

// Initial setup (like initialize_bodies)
~event setup {}
| ready i32

~proc setup {
    return .{ .ready = 1 };

// Main flow - matches nbody structure
