Re: [Boost-users] boost::bind with references

I have a function defined as

template<typename T> void foo(const T& x);

and then I use boost::bind(foo, x);

However, once the code is inside the body of foo, the addresses of x inside foo and the addresses of x when I called bind are different. So somehow a copy is being made. I can get around it by using boost::ref(), but is there a technical reason why it doesn't "just work" and pass it by reference

Capturing by reference is more dangerous because it can leave dangling references. In Christ, Steven Watanabe
