Re: Is it possible to pre-allocate a table with a specific size(i.e. pre-allocating the max memory that may be used by a table)?

In LuaJIT you can use `table.new` to create a table with a pre-allocated
array- and hash-part. Otherwise, it's only possible using the C API, but
I already built a small module to expose that API to Lua:
