Future of RubyVM
summary
Claim that CRuby remains the pragmatic choice for years because portability and easy C extensions beat heavy VM rewrites while never reaching peak VM performance due to opaque C code and conservative GC. Introduces lining: C Ruby mix yields ~10x speedups on iterators and up to 20x on hotspots, an AOT Ruby-to-C compiler that produces native modules and measurable speedups on loop and puzzle benchmarks, an atomic lby stripped interpreter for embedded use, and incremental GC cuts pause time to near constant.
