// Test 831: File processor (realistic I/O pattern with directory imports)
//
// Common pattern: read file -> process lines -> transform -> write output
// Tests: directory imports, multiple modules from same package, error handling
const std = @import("std");
// Import directory 'lib/io' containing:
// - file.kz (read, write events)
// - parse.kz (lines event)
// - transform.kz (uppercase event)
~import app/lib/io
// The full pipeline using directory imports
~app/lib/io/file:read(path: "input.txt")

Expected output
read input.txt
