014 scope for loop inner

✓ Passing This code compiles and runs correctly.

Code

// TEST: Scope - obligation INSIDE for-loop should auto-discharge per iteration
// STATUS: IMPLEMENTED
//
// When an obligation is created INSIDE a for-loop's | each |> branch,
// it should be auto-discharged at the end of EACH iteration.
//
// Here: We open a file inside the loop, so each iteration should close it.
// The [@scope] annotation on | each |> marks it as a scope boundary.
//
// Expected: Compiles and auto-discharges per iteration

~import "$std/control"
~import "$app/fs"

| each _ |>
    app.fs:open(path: "test.txt")
    | opened _ |> _  // Should auto-insert close() here, per iteration

Expected Output

Opening file: test.txt
Closing file
Opening file: test.txt
Closing file
Opening file: test.txt
Closing file

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 = .{} };
