Re: [boost] about function.hpp

I've haven't looked at the new stuff closely but I do have a couple 
of comments:

1) I really want to be able to use operator== to test if two 
callbacks have the same value. I have a lot of code that does stuff 
like this:

class ITimer {

public:
    virtual void AddTimer(function<void> callback, MilliSecond interval) = 0;

    virtual void RemoveTimer(function<void> callback) = 0;
};

This is nice and simple, but requires support for equality tests...

2) It'd be nice if there was a way

    // About
    function<void> action(this, &CApp::DoAbout);
    handler->RegisterCommand(kAboutCmd, action, kDisabledIfDialog, this);

    // Delete Color Formula
    action.Set(this, &CApp::DoDeleteColorFormula);
    function<SCommandStatus> enabler(this, 
&CAppMenuHandler::DoEnableDeleteColorFormula);
    handler->RegisterCommand(L"Delete Color Formula", action, enabler, this);

    // Delete Palette
    action.Set(this, &CApp::DoDeletePalette);
    enabler.Set(this, &CApp::DoEnableDeletePalette);
    handler->RegisterCommand(L"Delete Palette", action, enabler, this);
