Ticket #14711, comment 121
initial v1 48 48 I guess one could test `self._parent is None`, rather than typetest stuff. This should actually be faster. 49 49 50 Concerning "reasons": The parent is unset, because otherwise we have a chain of fromreferences from the map to the domain, namely via the parent (i.e., the homset). Hence, having a weak reference from the map to the domain would be futile if there is a reference from the map to its parent. Note that alternatively one could have a weak reference from the ''homset'' to the domain. But I think we have agreed above that we don't want this as a default.50 Concerning "reasons": The parent is unset, because otherwise we have a chain of references from the map to the domain, namely via the parent (i.e., the homset).
