I've been reading the discussion so far, and I agree that it would be
nice having some kind of syntactic sugar for such an operation, but
this is the only option which really makes sense for ;-)

  t[ #t + 1 ] = item   -- Sometimes hairy, as everybody says.
  t:append(item)       -- Implies lookup and function call.
  t[] = item           -- Seems that t will have a copy of all
                          the elements in "item" (like when you
                          do "x = y[:]" with Python slices).
  t[end] = item        -- I like it!

I was quite impressed by the implementation of "t[] = item" done with
the token filters patch. I did hear about the patch before -- but never
imagined it could make that tricky stuff because I didn't know too much
about it!

That were my two cents. Cheers,

P.S: Maybe I will be using Lua in my end-of-degree project at the
University ;-) If something interesting arises, I'll drop an email to
the mailing list.
