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|zig {}

// Another void event (like advance-positions)
~event step-two {}

~proc step-two|zig {}

// Branched event (like calculate-energy)
~event get-result {}
| value i32

~proc get-result|zig {
    return .{ .value = 42 };
}

// Print event with a result (like print-energy)
~event print-value { v: i32 }

~proc print-value|zig {
    std.debug.print("{d}\n", .{v});
}

// Initial setup (like initialize-bodies)
~event setup {}
| ready i32

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