I personally wouldn't like to have to write 'table.pack({}, ...)' every
time I wanted to pack the arguments into a new table.

On the other hand, having the table argument optional (either first, or
last) is not an option, because what would happen here?

function f(...)
  local t = table.pack(...)
end

f({})

Is the first argument a table that I want to fill, or an argument?
