LambdaConf 2017 Talk

I’m happy to say that my talk at Lambdaconf 2017 is finally posted!

In “I command you to be free!”, I motivate the virtues of reifying programs as values using the command pattern. The command pattern has a very natural evolution into the free monad, and it can be implemented in a way that’s idiomatic and convenient for both object oriented and functional programming languages. This strategy has worked well to improve the correctness and testability of the PHP codebase at work.
