Oops. I'm pretty sure Bill Hart was 100% just trying to make a joke. He wasn't at all serious.

And it doesn't matter for Sage, since we just delete the GMP you include and use MPIR. > Finally, I do not know what is all the fuzz about mpz_add occurrences > vs line number counts.

Richard Fateman posted a sequence of long flamebait emails to the sage-devel list criticizing our codebase for having too many occurrences of mpz_add. At some point along the way a question came up that you were ideally suited to answer, so I cc'd you. Bill Hart's email above would only be amusing in the context of that thread. Juanjo, please don't be offended by any of this or any misunderstanding. We are very appreciative of ECL, your contributions to it, and ***greatly*** appreciate how amazingly responsive you've been in helping us use ECL in Sage. Thanks!
