But that's precisely what we can't guarantee: unlike function
activations, the dynamic extent of a generator activation is unlimited.
We don't have finalizers, so we can't ensure that a finally block runs.
Otherwise browsers would be even more trivially DoS-attacked.
We went over this in 2006 and agreed then that finally cannot be
guaranteed. This is true even without generators:
function foo() {
try {
while (true);
} finally {
alert('so sorry');
}
}
foo()
Browsers must police infinte loops and offer to kill such runaways. The
finally can't run.
