[cpp-netlib-devel] Managing Tag Explosion

[Dean M. B. <mik...@gm...>]

Hi Guys,

I've been working on something that allows for better tag composition
in cpp-netlib. The idea is to actually now use template
metaprogramming provided by Boost.MPL to differentiate whether tags
denote certain properties. This should make tag specialization easier:

  struct foo : async, http {};

We can the query whether:

  is_async<foo>::value // either boolean constant true or false
  is_async<foo>::type // either mpl::true_ or mpl::false_

This makes overloading the policy dispatcher metafunction
significantly easier to extend.

Thoughts? Comments?

HTH
