Good point, I used `lambda metafactory` too in fury, but only for some `constructor/getters`. I implements some Function utils to generate lambda function, see

Good point, I used `lambda metafactory` too in fury, but only for some `constructor/getters`. I implements some Function utils to generate lambda function, see https://github.com/alipay/fury/blob/main/java/fury-core/src/main/java/io/fury/util/function/Functions.java https://github.com/alipay/fury/blob/main/java/fury-core/src/... I'm not sure whether `MethodHandle` can generate the most complicated code, since the serialization logic here are more complicated even than the manual written code.
