It is difficult to understand in which case nested_exception is applied.
[ Summit: ]
Alisdair will add an example in an update to N2619.

It doesn't appear that N2619 really addresses this. Alisdair to propose wording.

Mark issue 1008 as NAD, the type is adequately described.
nested_exception is intended to be inherited from by exception classes that are to be thrown during the handling of another exception, i.e. when translating from one exception type to another. nested_exception allows the originally thrown exception to be easily retained in that scenario.
