Is luaJIT a competitor to Julia, in the sense that you can write high-level code, without the need to call bits of compiled C / Fortran

My impression was that Lua at least was in the Python class of scientific computing, by needing to refer to optimized, precompiled libraries.

I have been using Terra lately as a C replacement for technical work, but SciLua seems to be a great way to stay with Lua for speed in these types of applications. I am curious if it is going to become faster compared to Julia at the 3 of 8 tests where Julia was faster.

How do you like Terra? Have you checked out Palleen or Titan?

I've looked at Palleen, but I haven't done anything with it yet. I am happy with Terra for now. Terra and Lua make a great combination, and mesh well. I am just trying to work them into my tasks.
