Recently arxiv submitted a new paper (Andrej Bauer, James E. Hanson, The Countable Reals) claiming an incredible theorem that Dedekind reals are not sequence-avoiding, and furthermore obtaining a topos that makes Dedekind reals countable.
I'm wondering if the constructive Eudoxus reals Eudoxus reals(see R. D. Arthan's The Eudoxus Real Numbers) are sequence-avoiding?
Also, if “all functions $\mathbb{Z} \to \mathbb{Z}$ are computable” holds, what will be the behaviour of Eudoxus reals? Would it become computable?
