// Test 656: User-defined flags appear in help
//
// Any library (not just stdlib) should be able to declare flags via
// ~std/compiler:flag.declare and have them show up in --help.
//
// This enables third-party libraries and user code to extend the CLI.
//
// Run: koruc input.kz --help
// Expected: Help shows --my-custom-flag in Backend Compiler Flags
~import std/compiler
// User-defined flag
~std/compiler:flag.declare {
"name": "my-custom-flag",
"description": "A custom flag defined in user code",
"type": "boolean"
}
// Another user flag with a value
~std/compiler:flag.declare {
"name": "optimization-level",
"description": "Set optimization level (0-3)",
"type": "string"
}
~event main {}
~proc main|zig {

# Currently FAILING - this test documents the expected behavior.
# Any code can declare flags and they should appear in --help.
