Unfortunately this may cause a performance regression, but I don't think there is an alternative that is both sound and backward-compatible. The regression could be fixed if impl specialization were available on stable Rust. |

Ill-behaved FloatCore implementations for user types could have `x.partial_cmp(&x) == None` even when `x.is_nan() == false`. This crate will now panic in those cases, rather than execute undefined behavior. Fixes #150.
