NaN propagation is not stupid. Frequently, components of a computation that end up being NaN turn out to be irrelevant at a later point, in which case the NaNs can be discarded.
Unfortunately, if a NaN reaches a comparison operation, it can lead to an end result that doesn't contain NaNs, but was still influenced by one. Ganesh
