This is great to hear, but it also kinda reinforces the point - .NET generics were reified from the get go, back when they were introduced in 2005. Java got generics a few months earlier than .NET, if I remember correctly; but we're still waiting for them to fully catch up. By the time it does, people coming from C# will be asking about things like sequence comprehensions (well, they already do, since those have been around for 8 years) and pattern matching...
