[Lazarus] record initialization

[Jürgen Hestermann]

when I try to initialize a record as in

----------------------------------------
var X : record
             A : Sizeint;
             B : boolean;
             C : Sizeint;
             D : boolean;
             E : Sizeint;
             F : boolean;
             G : Sizeint;
             H : boolean;
             end = (A : 0;
                    B : false;
                    C : 0;
                    D : boolean;
                    E : 0;
                    F : false;
                    G : 0;
                    H : false);
----------------------------------------

then this works as expected.
When omitting some entries from the end it works too:

----------------------------------------
var X : record
             A : Sizeint;
             B : boolean;
             C : Sizeint;
             D : boolean;
             E : Sizeint;
             F : boolean;
             G : Sizeint;
             H : boolean;
             end = (A : 0;
                    B : false;
                    C : 0;
                    D : boolean;
                    E : 0);
----------------------------------------

I only get a warning, that"Some fields coming after "E" weren't initialized".

But when I leave out variables in the middle or at the beginning as in:

----------------------------------------
var X : record
             A : Sizeint;
             B : boolean;
             C : Sizeint;
             D : boolean;
             E : Sizeint;
             F : boolean;
             G : Sizeint;
             H : boolean;
             end = (B : false;
                    C : 0;
                    D : boolean;
                    H : false);
----------------------------------------

then I get an error "Some fields coming before "B" weren't initialized" and it does not compile.

I found no words about this restriction in http://www.freepascal.org/docs-html/ref/refse23.html
Shouldn't it appear there?
It took me quite a while to find out why it did not compile
because omitting from the end works so why does it not work
when omitting from the beginning (or in the middle)?
