Extreme Cleverness: Functional Data Structures in Scala
Daniel Spiewak at Clojure Conj 2011
This talk will cover the theory and implementation of 6 unique functional data structures in Scala. We'll start out with the concept of functional persistence and then dive right into actual data structures. Each data structure will be motivated and built up by the associated theory and ideas. All of these will be illustrated (with requisite colorful diagrams) and implemented with the necessary trappings to be a first-class Scala Collection. Finally, we'll look at some of the real-world constraints imposed by hardware architecture and the JVM itself, touching on how these constraints affect data structure design in ways that the theory doesn't show.
