Passing function pointer in a variable

The Boost.Function library provides a good performance for pointers to functions, and it will not allocate memory on heap. Standard library std::function is also effective in storing function pointers. Since Boost 1.58, the Boost.Function library can store functions and functional objects that have call signature with rvalue references

boost::function<int(std::string&&)> f = &something;
f(std::string("Hello")); // Works
