You can use boost::function to store the result of a boost::bind expression:

http://boost.org/libs/bind/bind.html#with_boost_function

For instance, you might write:

boost::function<void(const A&)> bound = boost::bind(&A::f, _1);

depending on the signature of A::f.

Note, don't use 'new', just assign the value of boost::bind.
