[fpc-devel] generic forward declaration?

[Martin Frb]

Are there? Or is there something else?

The below compiles. No duplicate TBar. Looks like a forward declaration...

program Project1;{$Mode objfpc}
type
   generic TBar<A,B> = class; // forward

   generic TBar<A, B> = class
     F:A;
     X:B;
   end;

begin
end.



But the next does not compile "Identifier not found TBar" (inside TFoo). 
Yet the identifier is clearly there.

https://gitlab.com/freepascal.org/fpc/source/-/issues/24097 seems to say 
it is supported since 2022?

program Project1;
{$Mode objfpc}
type

   generic TBar<A,B> = class; // forward

   generic TFoo<A, B> = class
     F:specialize TBar<A>;
     X:B;
   end;

   generic TBar<A, B> = class
     F:specialize TFoo<A>;
     X:B;
   end;

begin

end.
