I feel like if we did that, then it would obviate the need for explicit `property.get` or `property.set` for most native Swift uses, though maybe not ObjC interop uses.

Agreed. I think there are a couple ways to approach that. We could resolve unbound property references contextually, so that Type.property gives you the getter in normal function context, or the lens in inout function context, and/or either allow implicit upconversion from lens to getter function or provide an explicit getter((inout T) -> inout U) -> T -> U adapter function.
