 Keywords:  any multimethod dispatcher  |  
----------------------------------------+-----------------------------------
 I tried to implement multimethod using Modern C++ Design's multi method
 technique.


 Multimethod.hpp::
    Multi method for boost::any.
    To specialize MultiMethod::Traits template, you can fit your
    boost::any like classes (check Holder.hpp).
    This class necessary
    loki/LokiTypeInfo.h and
 [http://groups.google.com/group/comp.lang.c++.moderated/tree/browse_frm/thread/4f7c7a96f9afbe44/c95a7b4c645e449f#doc_e5fbc9305539f699

 is_call_possible].[[BR]]
    And you must "entry" multi method before using multi methods.
    (same as Modern C++ Design's multi methods)

 Holder.hpp::
    Costomized boost::any for multi method.
    This class set unsigned int every class type to access
    multi method in constant time, and this class can also
    use multimethod holder.

 Please see attached main.cpp to check samples.
