Note that the author of the blog post explicitly mentions this FAQ item. Did you read the post at all?
Actually, he mentions a sentence inside the FAQ, and seems to ignore the rest of it. Did you notice that the FAQ Item was explicitly about working with Qt? And that the library is carefully designed to not be clobbered by the Qt preprocceser? (signals is only used for the namespace name, and slot(s) is never used, only slot_type). Simply put '#define BOOST_SIGNALS_NAMESPACE whatever' before '#include <boost/signal.hpp>' and everything works nicely.
I would not call this "nicely", that's more "klugely". What if I happen to write a library which used boost::signals in headers? Do you suggest me to use class My { public: boost::BOOST_SIGNALS_NAMESPACE::signal<.....> on_whatever; }; ? Do you mean that the current situation is optimal, and any attempts on improving it are just wasting time? - Volodya
