Tutorial on tag dispatching

by Crazy Eddie

From the article:

... There’s been some confused notions passed around recently that lead me to think there needs to be more information about probably one of the simplest, most powerful metaprogramming techniques that exist in C++: tag dispatching. The reason tag dispatching is powerful is that it leverages the language and the compiler to do work for you so that you don’t have to. It’s a technique whereby you use overload resolution rules to decide between otherwise ambiguous functions.

Concepts and tags

The first part to understand with regard to tag dispatching is the idea of “concepts”...

A Tiny Metaprogramming Library—Manu S├ínchez

Manu Sánchez is proposing a little-big collaborative challenge to the C++ community. Learning how to build:

A Tiny Metaprogramming Library

The proposal:

I hope you like this idea. It’s not only me writing crazy meta-stuff, but everybody developing their own metaprogramming library, learning something new each week, and comparing the different approaches each one is taking. I’m the guy who writes this posts, but I can learn a lot with your Tiny Metaprogramming Libraries and your feedback.
