Ruby: Where Are You Going?
summary
Ruby is 20 years old, with roughly 60 separate implementations ranging from MRI/CRuby (conservative GC, global VM lock, no JIT) to JRuby (no global lock, invokeDynamic JIT, Java interop and precise GC), Rubinius (bytecode VM, hacker-friendly), Maglev (object database + Smalltalk VM), RubyMotion and mruby (mobile and embeddable), and a new Topaz/partial‑evaluation effort that just appeared to use partial evaluation to precompute things like templates and eliminate intermediates while aiming for precise GC and faster runtime behavior.
