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`.
