It should be consistent, at least. I think the string assignment behavior
is the most reasonable: assignments return 1 but there's no assignment

I have reconsidered this. Making assignments that are supposed to be
ignored set $? to 1 means that a shell with errexit enabled will exit.
I don't think that's desirable. I don't think attempted assignments to
noassign variables should change $?.
