- This shortcoming will hopefully be fixed in the future.
+ Along with this behaviour comes the feature that it is possible to draw an
+ inverse sample from a :class:`ScalingOperator` (which is a zero-field).
+ This occurs if one draws an inverse sample of a positive definite sum of
+ two operators each of which are only positive semi-definite. However, it
+ is unclear whether this beviour does not lead to unwanted effects
+ somewhere else.
