Comment(by tibbe):
That looks much better. I'll stil need to figure out if I can get `test2`
to be strict in the buffer, as there's lots of reboxing going on. That's
outside the scope of this ticket.
Could we get this example turned into a test case? I'm not sure how to
write one, otherwise I would do so myself. We'll likely depend on the
arity analysis in the future, both in `binary` and `attoparsec`, and it
would be nice to be confident that the performance of those libraries
don't degrade dramatically in some future GHC version.
