If you wanted to divide and conquer we can, but actually I think another
thing that would be very helpful would be to have a more ergonomic way to use
aggregates as window functions. I could see two ways
1. Update `functions.window` to take an aggregate function instead of a
registered function name.
2. Add something like `Expr.over()` so you could do something like
`first_value(col("a")).over(window)` where `window` is a window frame
definition.
What do you think? That could be done entirely independent of this PR
