IMO, this is not a misuse. The throw/catch construct is
separate from begin-rescue-end and is often used in Ruby
for this kind of control flow issue...

Java, by contrast, has only one mechanism.

I'm open to debate, though.

And by the way, the Pythonism originally referenced is
certainly more elegant than the throw/catch example. I
wonder if it's useful enough to consider including?

Maybe it's one of those things you don't realize you need
until you have it.
