Looking at these pull requests, I wondered think, "Is it faster to implement some NilClass methods in Ruby?" method by Ruby code?". * https://github.com/ruby/ruby/pull/3264 * https://github.com/ruby/ruby/pull/3277 So I tried implementing some NilClass methods in Ruby: by Ruby. * https://github.com/ruby/ruby/pull/3366 benchmark: The following is benchmark, where `COMPARE_RUBY` is ruby 2.8.0dev (2020-07-27T15:18:40Z master c5ae79d7e9) [x86_64-linux] and `BENCH_RUBY` is ahead of ruby 2.8.0dev (2020-07-27T15:18:40Z master c5ae79d7e9) [x86_64-linux]: ```bash sh@MyComputer:~/rubydev/build$ make benchmark/benchmark.yml -e COMPARE_RUBY=~/.rbenv/shims/ruby -e BENCH_RUBY=../install/bin/ruby generating known_errors.inc known_errors.inc unchanged generating vm_call_iseq_optimized.inc vm_call_iseq_optimized.inc unchanged # Iteration per second (i/s) | |compare-ruby|built-ruby| |:-----|-----------:|---------:| |to_i | 36.563M| 60.801M| | | -| 1.66x| |to_f | 66.225M| 70.205M| | | -| 1.06x| ``` `COMPARE_RUBY` is `ruby 2.8.0dev (2020-07-27T15:18:40Z master c5ae79d7e9) [x86_64-linux]`. `BENCH_RUBY` is ahead of `ruby 2.8.0dev (2020-07-27T15:18:40Z master c5ae79d7e9) [x86_64-linux]`
