Nope...

for (auto i = ..., e = ...; i != e; ++i) {}

That form of for loop in C++ can be used for any range/container that
follows the iterator paradigm used by the STL. This is because <
requires random access iterators, but != works with any iterator.

Granted, since C++11, I prefer...

for (auto&& item : ...) {}

Mostly because this is more restrictive.
