I have two problems with it. One is that very few Schemers have used
it. I asked on this list once who had used it, and no one replied in
the affirmative. Therefore it is not "core" enough to go into a "small"
Secondly, its presence prohibits useful behaviors. For example, it
would be easy to make a `call-with-port' that closes its port on
exceptional exits by installing a throw handler. However, since throw
handlers are also used for raise-continuable, this is not possible.
