Hi,
Just a small question. What happens when an
exit/die instruction is
executed inside a using block? Is the relevant exitContext() handler
invoked, just like for an early return or break?
This is probably self-evident, but it is worth to state it explicitly, because, for some hysterical
reason, relevant finally blocks are *not* executed with exit.
