pitrou opened a new issue, #50250: URL: https://github.com/apache/arrow/issues/50250
### Describe the enhancement requested `arrow/util/functional.h` is a set of ad-hoc metaprogramming utilities that were necessary when Arrow supported C++11. Now that we require C++20, most of that functionality can probably be replaced by stdlib utilites such as `std::is_invocable` and `std::invoke_result`. This issue requires some C++ proficiency but hopefully little knowledge of the Arrow C++ codebase. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
