That's the same error you'd get when specializing outside of a generic with a 
non-class type.
I think you're right, my fault for not looking at the column close enough.


The "specialize" is part of the generic identifier, so it must be "FGL.specialize 
TFPGObjectList<T>".

That said however an internal error should not happen (especially the one I 
just added some days ago ^^'). Please report this one.

That doesn't look right to my eyes but ok. I filed a report 
(https://bugs.freepascal.org/view.php?id=36377).

The idea is that "specialize" belongs to the identifier just like "generic" 
does. This comes especially apparent for nested specializations:

SomeUnit.specialize SomeType<... >.specialize SomeFunc<... >
What's your plan to make an implicit specialize modeswitch? I remember you said 
you wanted to and it sounds like low-hanging fruit I could maybe help with. The 
specialize keyword is a bit much in my opinion and it sounds like it could be 
omitted like Delphi mode does.
Well, if you want you can find any place where the _SPECIALIZE and _GENERIC tokens are used and checked against mode Delphi to check against a new modeswitch instead ("GENERICKEYWORDS") which must be enabled by default in all modes except the Delphi ones.

Please note however that disabling the generic keywords also restricts some expressions that the compiler can handle as the Delphi syntax is not completly without ambiguity and not completly handled in the parser yet.

Sven
