Some typos I spotted in the RFC: "Structure patterns" -> "Object pattern" section: color: green​ should be color: 'green'​ (twice) "Future Scope" -> "Regex pattern" section: "idiation" should be "ideation" Also, to better justify the syntax for variable pinning, perhaps it might be worth mentioning that the caret character kinda looks like a pin? I'm not entirely sold on the syntax myself, but I think that visual association makes it easier to mentally parse. Finally, in the research document, I see there was some confusion about the C# syntax for variable binding. I think the idea is that the right-hand side looks like a variable declaration, so since int foo​ is how you define an integer variable named foo​, therefore it makes sense to reuse the syntax in bar is int foo​.
