> It doesn't make things worse, and the implementation isn't likely to add significant complexity.
> It retains consistency between ApplicativeDo and ApplicativeComprehensions (in contrast to the idea of making ApplicativeComprehensions perform a simpler desugaring, which came up during the discussion)
> A future proposal can add a simpler version of the desugaring for both extensions later.
