You are being snarky but I'll take immutability over types and interoperability and access to a vast and stable ecosystem over the simple and extremely limited and underperforming alternatives. Thanks for the segway. I also cannot understate the reasoning ease that comes with basically everything being a static, top-level function. Testing never requires mocks because you can redef any function anywhere trivially when you otherwise would reach for a mock which tends to be painful, complicated, and requires comlex mocking libraries. Even with immutability by default, you get an extremely performant platform that usually stomps on nearly all the dynamic languages you might otherwise choose like Python or Ruby etc. And you get first-class functions and a concise and extremely stable language that is a joy to program in. Thanks Rich and Alex!
