explains why operator[] returns a proxy. You can write:

int x = it[5]; it[3] = x;

to work around this problem.

Thanks, I'm just learning how to use boost.iterator library to make some of my code more generic. Maybe construction like "it[3] = it[5];" will not be used, but anyways it's result looks unintuitive.
