and operators for types that support them, like lists, dic- tionaries, and files. Definition: Container types, like dictionaries and lists, define default iterators and membership test operators (“in” too. 7 Prefer these methods to methods that return lists, except that you should not mutate a container while iterating over it. Yes: for key in adict: ... if key not in adict: ... if obj in alist: boilerplate. Choose the appropriate boilerplate for the license used by the project (for example, Apache 2.0, BSD, LGPL, GPL) Functions and Methods As used in this section “function” applies to methods

use assertions for this. If your code is a container that returns a size, be sure to use a type that will accommodate any possible usage of your container. When in doubt, use a larger type rather than calls to new commonly falls into this category, as does use of auto in a range-based loop over a container whose type is spelled out nearby. • (Allowed) When the type doesn’t matter because it isn’t being from boost/multi_index • Heap from boost/heap • The flat containers from Container: boost/container/flat_map, and boost/container/flat_set • Intrusive from boost/intrusive.
