Because std::find can only compare container elements with the given
element, not the addresses. You need to use something like (untested)
class ParAddressEqual : public std::unary_function<Paragraph, bool> {
public:
ParAddressEqual(Paragraph const * par) : par_(par) {}
bool operator()(Paragraph const & par) const {
return &par == par_;
}
private:
Paragraph const * par_;
};
ParagraphList::iterator it = std::find_if(pars_.begin(), pars_.end(),
ParAddressEqual(&par));
IMHO this is overkill if used only once, but is useful if you need it
several times.

I think we don't want one, see above.
