I tried this code:

struct Pattern(i32);

extern "C" {
    fn foo(Pattern(a): Pattern);
}

I expected to see this happen: parsing should succeed, but an AST validation pass should fail: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=c69d76225d2af005f0441b34b96e5a2a

Instead, this happened: gccrs failed during the parsing step
