let matches = expr.matches(&[CfgValue::Name("windows".tostring())]); asserteq!(true, matches);

let expr = parse("cfg(all(any(targetarch =\"x8664\", targetarch = \"aarch64\"), targetos = \"windows\"))").unwrap(); asserteq!( true, expr.matches(&[ CfgValue::KeyPair("targetarch".tostring(), "x8664".tostring()), CfgValue::KeyPair("targetos".tostring(), "windows".tostring()) ]) ); ```
