My point is that you may want to access some state of your invalid
program. State that is lost otherwise. But maybe just having the core
dump is actually enough, i.e. there is no other interesting state. You
are probably right that you can always recover from the error when a new
process is started. At least I cannot can up with a convincing case.

Since the current implementation does not follow the specification
regarding scope and finally block being executed in case of Error will
try ... catch (...Error) keep working? I have code that uses
assertThrows!AssertError to test some in contracts. Will this code
break?
