[Haskell-cafe] Agda's BUILTIN Naturals in Haskell

[Georgi Lyubenov]

Hey,

Is there any way to do something similar to what Agda does with natural
numbers via BUILTIN pragmas?
More precisely I want to have correct-by-construction natural numbers, that
at runtime are treated as `Integer`s. My initial idea was to abuse rewrite
rules to turn `data N = Z | S N` into `Integer` terms somehow, but I'm not
sure if this is possible.
