Description

This query has a fairly restricted view of what a valid bounds check consists of. Consider expanding to support iter != last as a valid bound check, if last is derived from end(). We should also consider the case of utility methods on iterators, and whether they are correct at the call site.

Example

for (; iter != end; ++iter) {
}
