[Solved] Can't specialize a generic class procedure

[Nimbus]

Hello,
I'm having a little trouble specializing a generic class procedure in objfpc mode.

Given the following - which works fine in delphi mode:

Code: Pascal  [Select][+][-]

1. program TestGeneric;
2.  
3. {$mode delphi}
4.  
5. type
6.   TSpeaker = class
7.     class procedure Say<T>(AMessage: T);
8.   end;
9.  
10. class procedure TSpeaker.Say<T>(AMessage: T);
11. begin
12.   Writeln('Says: ', AMessage);
13. end;
14.  
15. begin
16.   { Works fine here }
17.   TSpeaker.Say<Integer>(42);
18. end.
19.  

However, same thing in objfpc mode won't compile

Code: Pascal  [Select][+][-]

1. program TestGeneric;
2.  
3. {$mode objfpc}
4.  
5. type
6.   TSpeaker = class
7.     generic class procedure Say<T>(AMessage: T);
8.   end;
9.  
10. generic class procedure TSpeaker.Say<T>(AMessage: T);
11. begin
12.   Writeln('Says: ', AMessage);
13. end;
14.  
15. begin
16.   { Error: Syntax error, "<" expected but "." found }
17.   specialize TSpeaker.Say<Integer>(42);
18. end.
19.  

I wonder if I'm missing anything obvious here?

For reference, sumbled upon this while trying out TTask.Future<T> from System.Threading.
Free Pascal Compiler version 3.3.1-17704-gb20f968454 [2025/03/21] for x86_64

Thanks.

Ahh, I see - thanks @bytebites!
Didn't know it was the right syntax.
