TBH that was the spirit of my question. I was wondering if there was something special about Lua (the language), and it seems like the answer is a resounding "no".
I'm not sure I could call that "resounding" - for one a PyPy dev disagreed with him in a sibling thread.

What in your opinion keeps LuaJITs performance away from C/C++, i.e. what other "hard" things need to be solved?
