   my goodness, the is some serious engineering -- on using CPS and deep LLVM-fu to automatically generate an interpreter that is faster than LuaJIT's hand-coded interpreter https://sillycross.github.io/2022/11/22/2022-11-22/

     > LJR now has a feature-complete Lua 5.1 interpreter that is automatically generated at build time using a meta-compiler called Deegen (for “Dynamic language Execution Engine Generator”). More importantly, it is the world’s fastest Lua interpreter to date, outperforming LuaJIT’s interpreter by 28% and the official Lua interpreter by 171% on average on a variety of benchmarks.

     
     That's really impressive.
