Does it support select? Almost half of concurrrent programming use cases in Go are select related.
Could even use the return `await Task.WhenAny` to tell you the specific one to check. Shouldn't be a very hard construct to make; to make it more select like.
It has the benefit that any number of tasks can be selected, but the efficiency is not good as hard-coded select blocks.
But it looks C# Task.WhenAny has much less use case variants than Go select block.
