    Discussion

    This came up while clarifying wording for QVT13-33.

    The prohibition is presumably intended to ensure that all object creation has a corresponding trace record. A good idea but beyond the pragmatic integrity of QVTo. Untraced objects can be created in mappings anyway, so prohibiting their creation in helpers is just an unhelpful restriction on programming flexibility.
