Suppose I have a vector<Foo *> and I want to use indirect_iterator to create
an iterator that allows the user to read but not modify the objects pointed
to by elements of the vector. In other words, I want to do the following:
typedef /*whatever */ my_iterator;
my_iterator it(theVector.begin());
const Foo &foo = *it;
But I want
*it = Foo();
to fail. Also, if possible I would like this new type to interact with
indirect_iterator<vector<Foo *>::iterator>
in the expected way.
I'm sure this is possible, but the documentation doesn't really say how to
do it.
