[fpc-pascal] Override constructor in class helper?

[Thomas Kurz]

Hello,

what I'm trying to do is something like this:

TStringStreamHelper = class helper for TStringStream
  constructor Create;
  constructor Create (const AString: AnsiString);
end;

constructor TStringStreamHelper.create;
begin
  inherited Create ('', TEncoding.UTF8);
end;  

constructor TStringStreamHelper.create (const AString: AnsiString);
begin
  inherited Create (AString, TEncoding.UTF8);
end;  

Both ChatGPT and Gemini agree that this won't work because FPC resolves Create in this order:
1. Look at the real class (TStringList) for a matching constructor.
2. Only if no such method exists, check helpers in scope for a matching name.

However, if I try, the helper constructor *is* invoked.

Because I'm on FPC 3.3.1 trunk, I wonder whether this is indended behavior and I can rely on it in the future, or whether this is a bug and will break in the final 3.4.0 release.

It'd be nice if someone could clarify this.

Thank you
Thomas
