So, as Tim has pointed out, table.pack is what you want to make this work.

Something along these lines:

function Try( aFunction, ... )
  local aResult = table.pack( pcall( aFunction, ... ) )
  local ok = aResult[ 1 ]
  if ok then
    return table.unpack( aResult, 2, aResult.n )
  end
end

If you feel adventurous, you could easily build a simple try/catch/finally mechanism out of it.

On the other hand, perhaps this was a purely rhetorical question?!?
