ah alright, can you because infcx.const_eval_resolve returns TooGeneric even if the inference vars are unused. Please change this to

            Err(ErrorHandled::TooGeneric) => {
                assert!(uv.has_infer_types_or_consts(), "unexpected `TooGeneric` for {:?}", uv);
                NotConstEvaluatable::MentionsInfer
            }

uh that's just a bug with inconsistent where-clauses xx maybe change the assert to an if with a delay_span_bug for now? 😢
