Subject: [Rd] callCC in 2.7.0
Message-ID: <971536df0803300710t40f61256x78b9889a5c323924@mail.gmail.com>

Would anyone like to explain if callCC in R 2.7.0 gives
anything that on.exit does not already provide?

It seems that the exit condition once defined cannot
be added to overridden whereas with on.exit multiple
on.exit's add additional on.exits rather than being ignored.

Is this important?
