Hm. bind.hpp that I posted to the list works like this:

bind(&CApp::DoAbout, this);

which only differs by the version you want in the argument order. The
function object comes first for consistency (a member pointer is considered
a function object with an implicit 'this' as a first argument.)

What's uglier in this API?

The other bind usage is

bind(&CWidget::DoRedraw)

used in situations like this:

// vector<CWidget> w;
// vector<CWidget*> w;

vector<shared_ptr<CWidget> > w;

for_each(w.begin(), w.end(), bind(&CWidget::DoRedraw));
