> While it seems technically possible to construct nested FieldRefs, it doesn't seem that you can use them in practice. And it would also be nice to be able to get a nested FieldRef on an Expression. One solution could be to not handle this within FieldRefs at all and just handle it in Expressions: have a function like {{Expression GetField(Expression, name)}}.
