expression precedence table in introduction missing nameof(x)

https://github.com/dotnet/csharplang/blob/master/spec/introduction.md#expressions

|                                  | `default(T)`      | Obtain default value of type `T` |
|                                  | `delegate {...}`  | Anonymous function (anonymous method) |

should be

|                                  | `default(T)`      | Obtain default value of type `T` |
|                                  | `nameof(x)`       | Obtain the name of `x` as a constant string |
|                                  | `delegate {...}`  | Anonymous function (anonymous method) |

Thanks, good catch!

Since this isn't yet authoritative source, I'll keep these spec defects around for later application.

Not sure how much it is needed. Syntactically, a nameof expression is treated as an invocation expression.

The elvis operators are also missing (I'm not entirely sure how to even bring that up; are they unary in this table based on this?). I suppose it comes down to whether the table here is an authoritative source vs a high level summary of the language's expressions.

Syntactically to the rest of the spec nameof doesn't seem much different than checked(x), unchecked(x) or default(T) which are all in the table except for the quirk where it might not be a keyword and then becomes an invocation expression.

I'm closing this. This entire clause has been removed from the C# standard in V5. The new expressions are added in the expressions chapter in the correct location.
