Example failure: IDAllocator.h only pulls in AK/Hashtable.h, so any compilation unit that includes AK/IDAllocator.h without including AK/Traits.h before it used to be doomed to fail with the cryptic error message "In instantiation of 'AK::HashTable<T, TraitsForT, IsOrdered>::Iterator AK::HashTable<T, TraitsForT, IsOrdered>::find(const T&) [with T = int; TraitsForT = AK::Traits: incomplete type 'AK::Traits<int>' used in nested name specifier".
