Abstract
We report on our experiences in redesigning Scala's collection
libraries, focussing on the role that type systems play in keeping
software architectures coherent over time. Type systems can make
software architecture more explicit but, if they are too weak, can
also cause code duplication. We show that code duplication can be
avoided using two of Scala's type constructions: higher-kinded types
and implicit parameters and conversions.
