I agree that it makes no sense that there's no syntax in modern languages for concurrency. With structured programming we have single threaded stuff all figured out. There needs to be an equivalent for concurrency. Maybe it's incorrect to think it can be done with special types like Future/Promise or whatever. Where are the if, while, for, return, drop of concurrency?
