I uploaded to boost vault a new version of my implementation of Boost.Overload: /overload-mrcec/overload-0.2.1.zip , link: http://tinyurl.com/37647m Boost Overload behaves as an overloaded Boost Function. Actually it wraps multiple Boost Function objects of different signatures. What's new: I only fixed some issue after testing the code on more compilers. This is the current status: compiler OS test ------------------------------------------- gcc 4.1.2 under Linux pass intel 9.1 under Linux pass mingw 3.4.2 under Windows pass mingw 3.2.3 under Windows fail MS VC++ 8.0 under Windows pass MS VC++ 7.1 under Windows fail I arranged this and previous version in boost vault in a specific folder: /overload-mrcec You find a description of each version in the file README_FIRST.TXT, link: http://tinyurl.com/32hv3p You can read a preliminary introduction to boost overload here: http://tinyurl.com/3xtbyl The documentation has been kindly written down by Dean Michael Berris. You can read an informal tutorial here: http://docs.google.com/Doc?id=dfxvjncs_1x6456m Please report any bug, compiler issue, comment and suggestion. They are really appreciated.
