Object-oriented programming techniques allow the construction of reusable and extensible code. However, class-based languages have poor support for implementing type-orthogonal behaviour and extending nonleaf classes, which result in implementations with poor performance or limited functionality. This paper presents dynamic slots, a mechanism used to build efficient implementations of type-orthogonal abstractions. Dynamic slots can be statically type-checked and have been integrated into the
