[fpc-pascal] Open array compatibility

[Hairy Pixels via fpc-pascal]

Another question I just ran in to. Why isn’t "array of TMyClass” compatible 
with “array of TObject” open array? TMyClass is a descendant of TObject and 
dynamic arrays are compatible with open arrays right?

======================

type
  TMyClass = class
  end;

procedure MyProcedure(values: array of TObject); 
begin
end;

var
  myArray: array of TMyClass;
begin
  MyProcedure(myArray); // error: Incompatible type for arg no. 1: Got 
"{Dynamic} Array Of TMyClass", expected "{Open} Array Of TObject"
