This or that? Similar methods & classes in Ruby && Rails
summary
Practical differences matter: Range#cover vs include shows cover about twice as fast on small ranges and massively faster on huge ranges (include drops to ~27.7 it/s), regex choices matter too — match? avoids globals and is faster while =~ and others set Perl-like $~ globals, benchmarks run on Ruby 3.3.0, Mark IPS; monkey patching, class_eval and define_method have different boot/lookup costs; crazy eval-based method calling ends up ~281x slower, so pick the method whose semantics and side effects meet the real need.
