Err, sorry? Why is the example invalid because I am using the >> operator?

I could have used

write_config(config, s)

instead.

I think you may have missed the point: the operator >> (or write_config) 
  is a generic function and will work with any data type!

So while you have to write code for ReadSettings/WriteSettings again for 
every different actual 'Settings' definition, you don't have to do that 
if you are using the generic function. You simply *use* (rather than 
rewrite) write_config instead.

Don't mistake the operator>> used in the example for the standard 
iostream operator >>. The example is not writing the 'Settings' class as 
a binary blob. The operator >> is implemented by the lit window library 
and it is not a template.

Or did I misunderstand you?

Also, regarding the relevancy of the examples and the concept, have you 
had the time to look at the RssReader tutorial yet? Step 3 and 4 of the 
tutorial will be especially interesting.

Here's the link to step 4
