vec_equal_na / vec_detect_missing and NA

[ilikegitlab]

coalesce broke in my code since NA for list is now NULL. Although I can see where this coming from, lost of other R code (as.list(vector) in my case) is not converting NA to null, so its quite unfortunate. NA in lists are a real thing that people might want to check for (and coalesce). Would be great to get that functionality back.

We have been pretty happy with NULL as the missing value for lists and don't see that changing, so I think you'll need to come up with another solution. dplyr::case_match() may help.
