[cpp-netlib-devel] Modern C++

[K. G. <kim...@gm...>]

Hello all,

Pardon the noise...

This project caught my interest partly because it uses modern C++
techniques, and I'm not practically familiar with them. I've read
quite a bit about the techniques, so I think I understand them at a
theoretical level, but I don't have an intuitive sense of what to
apply when.

I've noticed the cpp-netlib code base uses a couple of idioms that I
don't really get:

1) tags -- I (think I) understand tag dispatching, but I don't see a
clear-cut reason to use a tag with the basic_client, for example...?
Is it just something to group traits around? I think I would have
naively built a message_traits class, that exposed the respective
typedefs, so I don't really see the benefit of the scattered traits
structs. Except maybe for the fact that they _are_ scattered, so they
can be specialized on a case-by-case basis?

2) directives -- I don't see what benefit these added over member
functions on the message... Help?

Thanks for any pointers,
- Kim
