foreach

• Finds places where you're detaching the foreach container.
• Finds places where big or non-trivial types are passed by value instead of const-ref.
• Finds places where you're using foreach on STL containers. It causes deep-copy. Use C++11 range-loop instead.

Note: range-loop is preferred over foreach since the compiler generates less and more optimized code. Use range-loop if your container is const, otherwise a detach will happen.
