For that matter, why even have NaN to begin with?
-
@nikomatsakis Exceptions are too expensive.
@samth Because they are expected to occur? Or it's just too painful having the machinery to manage them? If the latter, why signaling NaN?

-
@nikomatsakis I think the latter, and I've never seen a signaling NaN in the wild, but I don't really know. -
@samth@nikomatsakis i might be adding the support to haskell for ghc 7.10.
