How to remove elements from an std::set while iterating over it

How can I remove elements from an std::set while iterating over it

My first attempt looks like:

set<T> s;

for(set<T>::iterator iter = s.begin(); iter != s.end(); ++iter) {
    //Do some stuff
    if(/*some condition*/)
        s.erase(iter--);
}

But this is problematic if we want to remove the first element from the set because iter-- invalidates the iterator.

What's the standard way to do this?
