Closures: The next revolution in programming

In the 1950s Fortran released a great innovation into the world of software development: procedures. Suddenly, we could write programs orders of magnitude larger and more accurately than before. Then again, in the 1980s, Smalltalk and C++ introduced us to objects, and development took another great leap forwards. Now, at the start of the 21st century, another great leap forward is taking shape, and almost every language is adopting closures.

Closures really do introduce a whole new way of thinking about what programming is, and how to organise our code. In this talk, Jules will describe their beginning in Algol and functional languages, show how they work in modern languages, and demonstrate a few patterns and idioms that demonstrate their extraordinary power.
