Interesting. Under what circumstances are they broken?. Inf, NaN?

Here's an article on it that was posted awhile back: https://medium.com/@smcallis_71148/complex-arithmetic-is-com...

The gist is that you can get Nan+jNan for some operations where you wanted "infinity", so to do things their way, you have to insert a NaN check after multiplication for example. This isn't too bad by itself (it's just a bit mask), but it completely borks the vectorizer.
