Hi Dustin,

Here is a small doc patch based on answers from the list and from the
links mentioned. For stylistic consistency I've followed the language
in the va_arg description for the analogous situation.

as I mentioned in another email, unwind is not completely unsupported:
it does work for rethrowing an exception.

Ciao,

Duncan.

Good point. Not understanding how languages implement exceptions under
the hood, I lose the nuances that should be in a reference document.
How's this version?

PS: note that my text is very conservative because I am reluctant to say
anything about what invoke/unwind can do right now because, frankly, I
don't have the knowledge to get the details correct. It would be A Good
Thing, but needs a more knowledgeable author. But I think having the
note there in one place an interested person is likely to find it is
better than nothing.

I was tempted to put in some of the explanatory links I was given, but I
didn't because they might age badly and because that involves policy
choices about how and where information should be documented. I'll be
happy to add them to the patch if it's deemed appropriate, because
they're useful.

Dustin

Seems fine to me, committed as r93518, thanks!
