How much of a language is essential? Carl and Richard chat with Mark Seemann about what features are critical to a language, and which ones are redundant. Who would put redundant features in a language? Mark talks about how languages evolve, and how more advanced features can supercede older features, but the old features can never be removed without breaking existing code. And worst still, when building a language is your business, you'll add features whether they are needed or not - you need something new to sell! The conversation also digs into understanding languages more deeply - do you really need that if statement? Just because a feature exists doesn't mean you need to use it!
