Hey @jayceslesar Thanks for splitting out this task! For inspiration on how to name things, we try to keep in line with the Java library where possible. This makes it easier for folks to switch between the projects. In Java this would result in a [UnboundTransform](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/UnboundTransform.java). Unbound meaning that we don't know the type of the column yet. ``` CAST(created_at AS date) -> UnboundTransform(Reference("created_at"), DayTransform()) ``` Once we know the type, we can bind the transform and see if it is a valid cast.
