Hi,
You should not use the 'sink' function to save these data files. If
you want a readable format, you should look at 'dump' instead. If you
simply want to save your data structures then 'save' might be best.
'sink' is not appropriate for data saving. It's simply a convenient
way to log what you see in the terminal.
