Hey, I fully understand the concern that new short hands can lead to more convoluted code. There are many short hands we could consider adding to C#. We are extremely careful to only add ones that we think lead to more clarity in common code.
With any new opportunity to compact code, there's going to be people eager to overuse it. It's a bit of an organizational challenge to establish what good code looks like, and how these new features can be used responsibly, in a way that fits the culture of the company.
That said, we don't feel we have a choice but to evolve the language to improve developers' productivity and better meet new challenges. We try to take a balanced approach, so that C# can keep growing for a long time without collapsing under its own weight. But grow it will.
Thanks for all the wonderful comments, both good and bad ones!
