Why doesn't the compiler at least warn on this == null

http://stackoverflow.com/questions/2464097/why-doesnt-the-compiler-at-least-warn-on-this-null

here is why doesn't the compiler issue a warning for ReferenceEquals this null From the bottom of the above link A common error in.. to the overloaded operator causing an infinite loop. Use ReferenceEquals or cast the type to Object to avoid the loop. That might be.. And that's also why you should be doing object x null or ReferenceEquals x null not doing a simple x null when you're checking for null..
