Sorry, didn't mean to offend you.  I was just describing my initial
reaction.  I also didn't recall the specifics of your first proposal,
so I probably should have restricted my criticism to this one.

I still think there is way too much in it.  Where is MI suddenly
coming from?  If I recall correctly, we don't even have SI in Scheme
-- and I'm very happy about this fact.

Then: recoveries, restarts, ... this is what I call `bloat'.  For the
cases where you think you need the fancy stuff I am sure one can
easily come up with a straighforward way of doing it using plain old
`lambda'.

I would be perfectly happy with something as simple as
`raise'/`handle'.
