RE: Handling multiple selections in a Gtk::TreeView

I think they let you do stuff like this (I'm pretty sure I used them in Java
last year)

class someClass
	int data;
		// takes a function as an argument
		doSomeStuff (
					// actually define a function here,
without naming it, I forget the syntax
						++ data;

That's about the gist of it I think.

Yes, I think that get_selected_rows() was added sometime after
selected_foreach(), because it was more convenient.

I don't understand the comment about C++ not having anonymous functions.
Maybe that's C# terminology.

Actually, I can't think of a case when it is right now. If you think of
one, let's document it.
