I think that the case of rethrowing an exception with added detail is the worst
enemy of clean Exception hierarchies.
The idea of Variant[string] remedies that case without creating a new exception
class just for the added fields. If that case is solved, then the tipical need
for creating new exception types that don't really aid selecting them for
catching and recovery is solved too.
