> Currently in the Python layer we have {{ds.field(name)}} for referencing a field eg when creating a filter expression.
> On the C++ side, the {{FieldRef}} has the ability to reference nested fields (eg a child of a struct), for example constructed with {{FieldRef::FromDotPath}}.
> We should think about how to enable users to reference nested fields like this in the Python API.
