A baker's-dozen of insight crammed into one ring.
Summary
The Ruby core compiler team (including Aaron Patterson, Alan Wu, and others) announces ZJIT, a new just-in-time compiler for Ruby built into the YARV reference implementation. ZJIT aims to raise Ruby's performance ceiling through larger compilation unit sizes and SSA intermediate representation (IR), while also encouraging more outside contributions. It is now available with the release of Ruby 4.0.
