Follow-up Comment #3, bug #67845 (group octave):

Hi, I’m attaching a patch that enables classdef constructors to return
multiple outputs, matching MATLAB behavior.

Previously, constructors with more than one declared output were rejected, and
constructor calls always forced nargout = 1, so additional outputs were not
returned.

This patch:

Allows constructors to declare multiple outputs (first output must still be
the object).

Propagates the caller’s nargout when dispatching constructor calls in
meta_subsref.

Adds a regression test (test/bug-67845.tst).

I verified the original reproducer, checked negative cases (non-object first
output errors as expected), and ran make check (FAIL 0).

Happy to revise if any changes are preferred.
