Ah, you're right.

That's how Tom started, and I didn't follow the intention of using the
field name and suggested using the struct info.

But the real thing that you (Tom) are fighting with is trying to use
field names, where the struct info is disregarding that and keeps
around just the getter and setter names.  Looks to me like a better
approach would be to use the getter names instead -- possibly with a
macro that makes more convenient getters?
