Thanks for your reply. My confusion was due to an extremely unhelpful error
message (C2582) from MSVC 7.1.

The problem was that the Predicate class I was passing to filter_iterator
was not assignable and therefore the compiler could not automatically
generate the assignment operator for my class. Because filter_iterator
relies on the compiler for the default assignment operator, the error
message pointed to that class rather than to the Predicate class that was
the real culprit.
