FYI: (*it). vs it->

[Lars Gullik Bjønnes]

FYI:

Note that is some libraries the operator-> for iterators are missing
so 

for (vector<string>:iterator it = vstr.begin(); it != vstr.end(); ++it) {
        // print out one string at a time.
        cerr << (*it) << "Length: " << it->length() << endl;
}

is not guaranteed to work. However we have never experienced problems
with

        cerr << (*it) << "Length: " << (*it).length() << endl;

but hopefuly the problems it it-> are disapearing rapidly...
