Stop adding (polutting) new key word and syntax to C#. It is a complex programming language as of now. The more C# bloating with new stuff in each release (2.0, 3.0, 3.5, and now 4.0), the more it becomes a weaker programming language. Comparing
the number of keywords and programming constructs of C# to C/C++, Python, etc. and you will see how bloated C# has become.
How about try to provide new features without modifying language for a change.
