Yea, that's nice. I'll try to get it into docs.
But, BTW, did you notice that for just storing into a variable, you can use
("angle", po::value<double>()->notifier(&angle)),
? I.e. for simple case there's no need to use lambda.
Yet another good trick for the How to? Section or a related sample. Regards Hartmut BTW: attached just another patch I forgot to attach to my last message.
