winout << title("Example window") << button("Hello, world!") << wait_for(delete_signal);

I'm not necessarily pushing that exact approach, but just pointing out more C++-like alternatives.

I understand you're not pushing that approach. It couldn't quite work like that as you're trying to structure a tree rather than a sequence.

Not that I'm pushing the approach either, but if all your objects that can be parents have an insertion operator then building a tree is simple a matter of adding parentheses: tree << a << b << © << d << e << (f << g) ); or breaking it up f << g; c << d << e << f; tree << a << b << c;
