Hi George,

On 1, given that a filter can technically call a lot of other functions,
each of which may have finally blocks in them, we really ought to run those
finallies as the authors of those functions expected them to be run.

On 2, exception handling for a handled exception is considered complete
after the leave instruction of the catch block has been executed. The
exception object itself is just like any other object and won't be
discarded until a GC finds no references to it.

| Hi Jonathan,
|
| I would dare to ask you two more questions:)
|
| 1. If an inner exception cannot escape from the filter of the outer
| exception, can't we just discard the inner exception before executing its
| second pass?
|
| 2. when is discarded a “handled“ outer exception?
|
| My expected answer: in the suitable catch or filter handler upon the
“leave”
| instruction.
|
| Thank you very much in advance!
|
| Best regards,
| George
