032 nested for scopes

✓ Passing This code compiles and runs correctly.

Code

// TEST: Nested for-loops with resources at different scope levels
// STATUS: TESTING
//
// Three scope levels:
// 1. outermost_f - opened BEFORE outer loop, manually closed AFTER both loops
// 2. inner_f - opened IN inner loop, auto-closed in inner each branch
//
// This tests that @scope nesting works correctly with auto-discharge.

Imported Files

// Library module: fs
// Single disposal event - auto-discharge should work

const std = @import("std");

const File = struct { handle: i32 };

// Open a file - returns opened! state (requires cleanup)
~pub event open { path: []const u8 }
| opened { file: *File[opened!] }

~proc open {
    std.debug.print("Opening file: {s}\n", .{path});
    const f = std.heap.page_allocator.create(File) catch unreachable;
    f.* = File{ .handle = 42 };
    return .{ .opened = .{ .file = f } };
}

// Close - the ONLY consumer of [!opened]
~pub event close { file: *File[!opened] }
| closed {}

~proc close {
    std.debug.print("Closing file\n", .{});
    return .{ .closed = .{} };
