This is definitely a nice improvement which can lead to Ruby performance improvements.<p>It&#x27;s also worth noting that Ruby 3 in general will have a focus on performance. Matz talked about performance and the Ruby 3x3 effort during his RubyKaigi keynote. The goal of Ruby 3x3 is to make Ruby 3 be 3 times faster than Ruby 2.<p>Full disclosure: I work for AppFolio which is helping to sponsor the Ruby 3x3 effort.
