[fpc-pascal] Class reference doubt

[Jesus Reyes]

in the following example The output is:
cls class is TFoo
TObj.create

where I would expect:
cls class is TFoo
TObj.create
TFoo.create

ie the TFoo.constructor is not called, is this normal/expected?, The documentation does clarify the situation: http://www.freepascal.org/docs-html/ref/refse31.html 

"Class reference types are used to create instances of a certain class, which is not yet known at compile time, but which is specified at run time. Essentially, a variable of a class reference type contains a pointer to the definition of the speficied class. This can be used to construct an instance of the class corresponding to the definition, or to check inheritance." 

Thanks.

program test;
{$mode ObjFpc}{$H+}
type
  TObj = class
  public
    constructor create;
  end;
  TObjClass=class of TObj;

  TFoo = class(TObj)
  public
    constructor create;
  end;

constructor TObj.Create;
begin
  inherited create;
  WriteLn('TObj.create');
end;

constructor TFoo.create;
begin
  inherited Create;
  WriteLn('TFoo.Create');
end;

var
  cls: TObjClass;
  obj: TObj;
begin
  cls := TFoo;
  WriteLn('cls class is ',cls.ClassName);
  Obj := cls.Create;
  Obj.Free;
end.
