Review Comment:
Thank you for the review and approval, @peter-toth. Yes, a lambda body has
the same gap, and I reproduced all three of your examples on this head. It
needs a different change, which tracks the arguments of the enclosing lambda
functions as you suggested, so I'd like to keep this PR to struct fields. I'll
file a JIRA issue and open a separate PR for it on top of this one.
