A. The main building block is the concept of a Formatter (sketched below). There will be a number of built-in formatters, such as 1. sequence_formatter, for formatting objects of a type I.A.1. using specified opening, closing and separator strings 2. nary_formatter<N>, for formatting objects of a type I.A.2. Nary formatters can be specified with expression templates -- e.g.,
str("[") << _2 << " : " << _1 << ")"
Forgot to mention in the previous email: I recall that when I was trying to write my own code for this task, I found very usefull to number elements of a sequence. I still have handwritten code for dumping some data which numbers the elements. That's handy when elements are referred by indexes.
I'd like such a formatter to be a part of the library; I know there's such example already, but I'd rather see a documented part of a library, not just an example.
I think Reece has an example of this. Of course it's easy to do with my framework too. Jonathan
