Supporting Files

// Library module: fs
// NO disposal event defined - should error

const std = @import("std");

const File = struct { handle: i32 };

// Open a file - returns opened! state (requires cleanup)
~pub tor open { path: string } -> *File<opened!>

~proc open|zig {
    const f = std.heap.page_allocator.create(File) catch unreachable;
    f.* = File{ .handle = 42 };
    return f;
}

// Oops! No close() or any event with <!opened> defined!
// This is a library bug - no way to satisfy the obligation
