Exactly, I would prefer the injection/extension to Lua in a simpler
manner - if Lua/LuaJIT didn't recognize the annotation, it would just
silently ignore it, while leaving the room for additional parsing or
post-processing.

The idea is just simply to have the interpreter be able to parse the
source code without additional compiling steps - which could be
un-productive IMHO.
