I take this back. I've read all Mike's post in the lua mailing list, and found the reference where he talks about it, and in fact as not considering it (yet) it was from old posting in 3/14/2006 5:50PM: "* Garbage collection and heap allocation put Lua at a speed disadvantage to languages with manual memory management. The impact is less in Lua than other dynamic languages because of typed-value storage and immutable shared strings. Adding a custom memory allocator to the Lua core could be beneficial. Complex solutions like escape analysis are not on my radar for LuaJIT (yet). "
