I don't think you are missing something. My point has nothing to do
with the manual. I just prefer the solution without 'lines'/'gmatch',
independently of whether you need to keep a state. (I think it is
simpler, because 'read' is simpler than 'lines' and 'find'/'match'
is simpler than 'gmatch'.)

Otherwise, I guess the manual is clear about these two functions
returning only an iteration function that can be called (with no
specifed parameters) to get a "next" element.
