I want to use indirect_iterator and noticed that it subscript operator
returns a proxy.
I found the following explanation in iterator_facade.h:
// A proxy return type for operator, needed to deal with
// iterators that may invalidate referents upon destruction.
// Consider the temporary iterator in *(a + n)
But I still don't understand why a proxy is necessary in some cases.
Thank you in advance,
