You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/bevy/crates/bevy_ecs/macros/src
    
    the code of the file until where you have to start completion: // FIXME(3492): remove once docs are ready
#![allow(missing_do
    
pub fn derive_system_set(input: TokenStream) -> TokenStream {
    let input = parse_macro_input!(input as DeriveInput);
    let mut trait_path = bevy_ecs_path();
    trait_path.segments.push(format_ident!("schedule").into());
    let mut dyn_eq_path = trait_path.clone();
    trait_path.segments.push(format_ident!("SystemSet").into());
    dyn_eq_path.segments.push(format_ident!("DynEq").into());
    derive_label(input, "SystemSet", &trait_path, &dyn_eq_path)
}
