> The goal of this improvement is to add compile time type-safety to dependency injection of Lists and Maps.
> *Proposed changes in DI API*:
> Add following methods in {{Binder}} interface
> {code}
>     <T> MapBuilder<T> bindMap(Class<T> valueType);
>     <T> MapBuilder<T> bindMap(Class<T> valueType, String bindingName);
>     <T> ListBuilder<T> bindList(Class<T> type, String bindingName);
>     <T> ListBuilder<T> bindList(Class<T> type);
> {code}
> And deprecate non type-safe methods:
> {code}
>     <T> MapBuilder<T> bindMap(String bindingName);
>     <T> ListBuilder<T> bindList(String bindingName);
> {code}
> *Incompatibility*
> If Cayenne DI is used in third-party code (custom modules or Cayenne modifications) the code should be updated if bindings other than {{List<Object>}} and {{Map<String, Object>}} were used, as this code will be broken.
