How does it handle alignments? The arrays of opcodes inside a compiled
bytecode are not necessarily aligned (at least not in the standard format
that Lua uses to represent binary code).

eLua has a "ROM file system", which is basically a bunch of files and some metadata about their names arranged in a contiguous memory area. The alignment for the files can be controlled at compile time, when the ROMFS is created, so any bytecode file can be aligned in memory as needed. I think the current alignment is 8 bytes, but I'm pretty sure that 4 bytes also worked.
