I don't think such use cases are supported. Generally, reinitializing an 
object by calling __init__() explicitly is not well-defined, except when 
advertised explicitly in the documentation. The only property we should 
guarantee here is that it doesn't lead to an inconsistent object state, or to 
hard crashes. Raising an exception is fine, and changing the raised
exception to another one should be fine as well.
