Nevermind.  I realize you didn't say that LuaJIT was faster than g++,
just faster than DMD.    But that last part made it sound like you
thought LuaJIT was on track to eventually outperform all compilers.
As in the need for fast JIT is strong enough that eventually people
will figure out how to make it faster than everything else out there.
