I presume then TList<> and TList class are not implemented the same then because I still don’t know how the generic itself affects runtime performance.
Btw this looks like C# code because C# explicitly does not specialize at compile time but rather runtime so every instance will be using TList<Integer>. Does Delphi do this also? I think FPC requires you MUST specialize at compile time so simply using TList<Integer> won’t compile.
