[fpc-pascal] Errors using Extended Class Syntax

[bsquared]

Hello,

I followed the example on the wiki page, but the compiler disallowed 
both of the following attempts.

{$mode objfpc}{$H+}

TExample1 = class
private
   const
     CN_CONST = 'EXAMPLE CONSTANT';
published
   property Example: string
     read CN_CONST;
end;

Error: Unknown class field or method identifier "CN_WELCOME"

TExample2 = class
private
   fExample: string;
   const
     CN_CONST = 'EXAMPLE CONSTANT';
published
   property Example: string
     read fExample
     write fExample
     default CN_CONST;
end;

Error: Property can't have a default value

I can work around this by using a getter method which can read the 
private constant field, but I am curious why these attempts did not work.

Also, What is the static keyword on the class method?
class procedure SetSomeClassVar(const AValue: TSomeType); static;

Thank you.
