There is another way you can do it ... That can be found in the Lisaac
language (pretty unknown at the moment, but I like it much).

You can define an escape sequence that could be written \%s+\ and that
does nothing. For instance your example could be written:

   if something then
      for k,v in pairs(foo) do
         if v then
            bar()
         else
            io.write "This is a big chunk of text \
                     \that for whatever reason (typically \
                     \readability) is broken into multiple \
                     \lines in the source code.\n"
         end
      end


And this does not create ambiguity with the call syntax.
