cleanProjections :: NonEmpty Projection -> NonEmpty Projection Source #

TODO: For now, we're littering this around where projections are built. I'd prefer to use ordered set, or else a newtype wrapper to prove it's been sorted. But that would interrupt code elsewhere. For now, this is an acceptable solution. Plus, a warning issued about duplicates might be useful.
