> *Umbrella ticket*
> At the moment {{Table.filter}} only accepts a mask, and building a mask that
> actually leads to the rows we care about can be complex and slow in cases
> where more than one compute function is used to generate the mask. It would
> be helpful to be able to pass an {{Expression}} as the argument and get the
> table filtered by that expression as expressions are easier to understand and
> reason about than masks.
