Re: [Boost-users] Visitor Pattern Implementation

Do you mean the Observer pattern, or are you just talking about boost::visit_each? I'm not aware of anything about visit_each that makes it inherently unusable in a multi-threaded program. Boost.Variant uses visitors. You could look at the BGL too, which also uses visitors.

I mean Visitor Pattern, by means of boost::visit_each. Thank you for you input!
