I would not take pattern matching as the right example. I learned pattern matching at the university and always missed it in C#. It is easy and straightforward. When you love lambdas and linq, so C# 3.0, pattern matching is easy.

However, when it comes to modern C# and memory management I also think that readability suffers a lot. Memory management on that level is well known to the professional C/C++ folks but most of us are just overloaded with it.
