I was referring to the released version of pipes-core, for which
"known to be unsound" is an accurate description.  Good to hear that
you've got a fix coming, though.  Given the history here, maybe
working out the proofs of the category laws sooner rather than later
would be a good thing.  I'll have a look today and see if I can bang
out a proof of the category laws for your new code without ensure.

It will then be interesting to see how that compares to Gabriel's
approach, which at this point we've heard a bit about but I haven't
