The review of the Egg library by   Shunsuke Sogame  starts today.The library is concerned with the implementation and adaptation of function objects. As function objects are everywhere in Boost and C++, I hope to see plenty of discussion and votes during the review.

Introduction:
    It is not so easy to define Function Objects
    especially if you want to support Boost.ResultOf and Boost.Lambda.
    Therefore, as Boost provides iterator_facade and iterator adaptors,
    Egg provides function_facade and function adaptors.

Egg provides the following features:

    * Workaround for the Forwarding Problem
        http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1385.htm

    * Helpers to build Function Objects:
        * egg::function and egg::function_facade provides the way to
          build Function Objects which supports Boost.ResultOf and Lambda.

    * Function Objects Adaptors(in other words, higher-order functions):
        * egg::curryN supports the currying.
        * egg::pipable emulates extension methods(C#).
        * egg::fuse/unfuse emulates variadic functions.
        * egg::nestN represents nested lambda expressions.
        * etc...

The documentation is on line:
  http://p-stade.sourceforge.net/boost/libs/egg/
The zipped source code is in Vault/FunctionObjects:

Tested under:
  Boost Development Trunk and Boost Version1.34.1.
 
---------------------------------------------------

Please always state in your review, whether you think the library should be
accepted as a Boost library!

Additionally please consider giving feedback on the following general
topics:

- What is your evaluation of the design?
- What is your evaluation of the implementation?
- What is your evaluation of the documentation?
- What is your evaluation of the potential usefulness of the library?
- Did you try to use the library?  With what compiler?  Did you have any
problems?
- How much effort did you put into your evaluation? A glance? A quick
reading? In-depth study?
- Are you knowledgeable about the problem domain?
 
Thanks
