> For compatibility, we need support for expressing window functions. Window
> functions are different from regular unresolved expressions as they need a
> window spec and are generally treated more like aggregate functions.
> Part of this task is to identify if we can fully express the logic of window
> functions using unresolved functions with expression arguments that represent
> the window spec.
> Only once this validation is done, we should consider adding a new plan
> operator / expression type.
