There's a similar comment from the earlier thread [1]:
"I urge designers of future dynamic languages to study Lua and LuaJIT if you want your language to not inhibit JIT development."
and [2]:
"Agreed. Also Smalltalk's memory model was a lot easier to optimize than languages like Python and Ruby. (Java inherited some of that.) Not having syntactic sugar makes optimization easier.
In addition, language designers need to make parser tools easy to make and robust."
