{$mode delphi} and dynamic array initializers, is there a modeswitch?

[prof7bit]

This works in delphi mode:

Code: Pascal  [Select][+][-]

1. program Project1;
2. {$mode delphi}
3.  
4. type
5.   TArr = array of Integer;
6.  
7. const
8.   // objfpc would not allow me to use these kind of
9.   // initializers or any kind of dyn array initializers
10.   // that I am aware of at all. Delphi mode does!
11.   Foo: TArr = [1,2,3];
12.   Bar: TArr = [1,2,3,4,5];
13.  
14. begin
15. end.
16.  

Do I really need to set the unit to Delphi mode for this to work or is there also a {$modeswitch xyz} where I can just turn on this one feature?

I'm now going to answer my own post:

Instead of [] just use () and it works. I think I should read the release notes of new FPC versions more carefully, until 5 minutes ago I was 100% convinced it would not be possible in FPC.
