Maybe it should be clarified that there are exceptions in
H98, but *only* in the IO monad.  What the extension is
about are exceptions in pure functions.  As for the FFI and
concurrency, I agree with you, but these are also the two
extensions of which it is very clear how to do them by now
and it is more a matter of getting all implementations in
sync.  Languages like Perl and Python don't have this
problem.  There is just one implementation and that defines
the language.

Otherwise, I can assure you, Haskell has a rather complete
feature set and is ready for serious use.

    the net effect is the same.
