## Always Use Namespaces
There is almost never a reason to declare an identifier in the global namespace. Instead, functions and classes should exist in an appropriately named namespace or in a class inside of a namespace. Identifiers which are placed in the global namespace risk conflicting with identifiers from other libraries (mostly C, which doesn't have namespaces).
