This talk is about the evolution of Python. We will discuss Python 2 and Python 3: what the compatibility issues are, what the main differences are, and also talk about migration, Python 2.6 & 2.7, and other transition tools.
Seph is a new experimental language. It is based on pure differential prototype based object orientation, with immutability and polymorphic dispatch built in deep. Seph uses the new features in Java 7 to full effect, by compiling highly dynamic code to use method handles and invoke dynamic. It's got light weight threads and the mature concurrency primitives from Clojure.
Object-functional languages have a number of desirable properties and have proven very useful in practice. Unfortunately, the merger brings with it a raft of complexities, being the root of nearly all of Scala's infamous complexity. This talk will present a new framework for resolving these issue, based around the notion of statically-typed functional object prototypes.
