I think so.  Once strictness is lost, there's nothing the user of a
library could do about it.  If a container is too strict however,
lazyness can be recovered by wrapping values in an additional data type.
So strict variants of updating functions would be a big win, and if two
versions of every function are deemed too much of a burden, I'd rather
get rid of the lazy version.
