Re: [boost] [asio] wrapping handler with tuple in serialization example, client.cpp, connection.hpp

Hi, I was wondering the same thing but Chris explained before

http://article.gmane.org/gmane.comp.lib.boost.asio.user/136

Have you replaced the tuples in all handlers and tested the example ?  I'd
prefer to use boost::protect too but there may be a small performance
penalty by having to use boost::function instead of a regular function
pointer. It would be good to know whether this performance penalty is
negligible or not
