The majority of issues are caused by the usage of the quote which exported from other crates. For instance, such instances occur in leptos_macro:

#[macro_use]
extern crate proc_macro_error;

use proc_macro::TokenStream;

#[proc_macro]
pub fn view(_a: TokenStream) -> TokenStream {
  quote!{};
  TokenStream::new()
}

and the reduced was:

// extern-1
#[macro_export]
macro_rules! quote {
    () => {}
}

// extern-2
use extern_1::quote;

// code.rs
#[macro_use]
extern crate sera_2;

fn main() {
  quote! {};
}

bvanjoi · 2024-01-01T17:35:10Z

Should we consider adding a lint for this issue?
