'@' as sugar for 'self.' can be done with a simple token filter:

/*
* proxy.c
* lexer proxy for Lua parser -- implements '@' as sugar for 'self.'.

* This code is hereby placed in the public domain.
* Add <<#include "proxy.c">> just before the definition of luaX_next in llex.c

static int nexttoken(LexState *ls, SemInfo *seminfo)
{
	int t=llex(ls,seminfo);
	if (t=='@') {
		t=TK_NAME;
		seminfo->ts = luaS_new(ls->L,"self");
		ls->lookahead.token='.';
	}
	return t;
}

#define llex nexttoken
