:class:`Operator` supports the multiplication with a scalar. So one does
not need instantiate :class:`ScalingOperator` explicitly in most cases.
Formally, this operator always supports all operation modes (times,
adjoint_times, inverse_times and inverse_adjoint_times), even if `factor`
is 0 or infinity. It is the user's responsibility to apply the operator
only in appropriate ways (e.g. call inverse_times only if `factor` is
This shortcoming will hopefully be fixed in the future.
