Namespace qualifier

Is it possible to create a namespace named "system" in our application. I have tried to create a class under the namespace of " System"in my application which ends in a compile time error. I tried to fix this error. But i couldn't. When i google it, i found a nice article from msdn to avoid this error. We can use the existing System namespace by using global::System to avoid the compile time error.
