Since issue http://bugs.freepascal.org/view.php?id=13256 was marked resolved,
I think this is quite reasonable to expect this to work.
The writeability of constants is IMNSHO just an ugly leftover from
Delphi history,
and should be disabled in _both_ delphi and objfpc modes:
Making typed constants writeable has been a disputed feature of the
Borland dialect, I agree with that, but fact of the matter is they are
writeable and thus cannot form a constant expression. The fact that there
exists a $J directive does not change this.
There are some estethic arguments against this: allowing them into
initalization results in a break of the separation between declarations
and code Pascal has: The declaration suddenly gets an assignment statement
built-in.
I forsee also practical problems: Procedure initialization code would
become much more complex. Rather than storing a fixed value in a variable
one would need to take care of dynamic types, like ansistring management.
