009 multiple taps

// Test 310_009: Multiple Taps on Same Event (Library Syntax)
// Validates that multiple ~tap() declarations all fire
// NOTE: Taps fire in REVERSE declaration order (last declared = first to fire)

const std = @import("std");
~import std/taps

// Event with an identity branch for the taps to observe
~tor hello {} -> string

// Void observer events
~tor tap1 {}

~tor tap2 {}

~proc hello|zig {
    std.debug.print("Main flow executed\n", .{});
    return "go";
}

~proc tap1|zig {
    std.debug.print("First tap observed!\n", .{});
}

~proc tap2|zig {
    std.debug.print("Second tap observed!\n", .{});
}

// First tap on hello
~tap(hello -> *): v |> tap1()

// Second tap on hello (should also fire!)
~tap(hello -> *): v |> tap2()

// Execute hello - should trigger both taps
~hello()
