When should I make explicit use of the `this` pointer?

Question

When should I explicitly write this->member in a method of a class?

Answer 1

One other case is when invoking operators. E.g. instead of

bool Type::operator!=(const Type& rhs)
{
    return !operator==(rhs);
}

you can say

bool Type::operator!=(const Type& rhs)
{
    return !(*this == rhs);
}

Which might be more readable. Another example is the copy-and-swap:

Type& Type::operator=(const Type& rhs)
{
    Type temp(rhs);
    temp.swap(*this);
}

I don't know why it's not written swap(temp) but this seems to be common.
