First of all, I'm using boost 1.55.0 on MSVC9. I've been using boost::phoenix in various places in my code base for easier usage of std::for_each and friends. However, I do not create lazy functions for a lot of the functions I bind to because they are only needed in one place most of the time. As a result, I use boost::phoenix::bind the same as I'd use boost::bind(). However I have read in various places that boost::bind is being deprecated. I'm not sure if there is truth to this, but is there a reason to choose one over the other? Is phx::bind() basically an "upgrade" to boost::bind? If I intermingle them, I have a lot of issues out of placeholder ambiguities that results in more boilerplate code (i.e. using boost::phoenix::placeholders::_1 everywhere). Any tips? I haven't used boost in a few years so I just want to make sure I'm not using it incorrectly. Thanks in advance.
