Video of my invokedynamic talk is online!
Several Edumenters attended Build Stuff 2013, and two of us gave talks. All of them were recorded by InfoQ, and they’re now starting to appear online! The first one to appear is my invokedynamic talk. The invokedynamic instruction was introduced in JDK7, and was aimed at helping compiler developers targeting the JVM to more efficiently implement a wide range of language features. While the name suggests a role mainly for the things we like to call dynamic languages, invokedynamic has in fact been used as part of implementing lambda expressions in Java 8.
My own application of invokedynamic was implementing JVM support for the Rakudo Perl 6 compiler. While the talk is not just about that – it covers invokedynamic in a much more general sense – I was able to draw on my concrete experiences of using it, which is something I always like to be able to do in a presentation. Also it was nice to do a talk on compiler-related things – an area I greatly enjoy working in.
