Token filters are an experimental add-on to Lua 5. They've been
discussed extensively on the list, and there are a couple
alternative implementations currently.
In short, they will allow one to "cut in" the token stream,
modifying syntactical things as long as the outcoming stream
remains valid Lua tokens. In the exhibited case, one would simply
add "nil" where two consequtive commas occur. In practise, it is
not quite as simple as this.
Alternatives to experiment with include lhf's token filter patch,
my fsyntax.lua/ftools.lua which builds upon it (adding syntax
awareness), and MetaLua (which in my opinion has way too complex
expressions, but I'm biased... ;)

I am interested in this and I am a bit new to Lua, so can you
explain this a bit more?
Thanks.
