[DUG] class variables - bad language definition

[Myles Penlington]

Then does 

type
   Taa = class()
   private
     class var xx : yy;

   private
      zz : integer
  public



Work as expected? I.e zz is an instance variable?

Another pitfall for young players.

type
   Taa = class()
   private
     class var xx : yy;
      zz : integer
  public


The xx declaration makes all other variables after it class ones as
well.  I know its documented, but one doesn't realise the impact until
after falling in the hole.  And the hole remains in my code for a future
developer to fall into.  This is specially bad after being used to the
class function declaration which works differently.

I hate this sort of stuff, the code can not become more robust if a
declaration of a new variable affects previous declarations.
