Why don't nullable relational operators return bool? instead of bool?

I think the above is applicable to C# 2.0 It will be better if the version to which the faq is applicable is mentioned because "int?" and "nullable bool" sent me googling for them and I spent some real worried moments trying to figure out that its a new thing and its not a concept/feature in the existing C# version.

Do you know where to come with an opinion on the new syntax? I hate it. I ruins one of my best selling points for C#: The syntax is simple and readable.

Now we can have "??" and "int?". Well, this doesn't help to make the code readable.

On the other hand maybe obfuscators is not needed any more ;-)

Is this sort of question-mark syntax in the 2.0 specification or is it for a future version of the language, such as C# 3.0? Is the question mark a shortcut for the Nullable generic?

I am very glad that you decided that the relational operators will return a bool (true/false). If relational operators returned a tri-state value (true/false/null) it would make the language unbearable.

I found the answer to my question in section 24.1 of the C# 2.0 Spec:

"The syntax T? is shorthand for System.Nullable<T>, and the two forms can be used interchangeably."
