No, it was deleted from Sourceforge and I have no copy.

It is hard to say, but I would tend to ignore the performance
issue, at least at first. For some types such as:
'a option
where you have a
match x with Some y -> ... | None
inside a tight loop there may be a small difference.
I haven't done any serious performance tests though.

I thought exceptions were just a weak form of
polymorhic variant.
