## Summary:
One sharp edge of the new `bindings` setting (when used for composite
types) is this: the (presumably struct) type to which you're binding
may expect to have particular fields, but it's GraphQL so you could have
requested some other set of fields. Now, if you ask us, we check.
Specifically, I've added a new setting under the `bindings` items, which
says: everywhere we query this must select these fields. (Or use its
own inline `# @genqlient(bind: ...)`.) It must select exactly those
fields, in order, no more, no less. This was fairly easy to implement;
actually comparing the selections was surprisingly much code but it's
all pretty straightforward.
