You might opt to wait a year or so, to see how (and if) token filters
get adopted to mainstream in some way or another.
..or at least wait until the end of the year. Every language
community has stable and experimental features. This one is still the

Since this is an add-on, does that mean you'd have to work with the
lua source itself to get this working? If so, then It's a little
beyond me as I've never worked with C, I've been working with
FreeBasic and pre-compiled lua libraries

Token filters are an experimental add-on to Lua 5. They've been

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... ;)

That would naturally not be valid Lua. However, the effect
achievable with token filters.
I am interested in this and I am a bit new to Lua, so can you
explain this a bit more?
