Ah, right, you'd have 1 reverse iterator on one side of the 'zip'. Thats
unfortunate. I guess this reads well-enough though, iti s definitely an
improvement.

Just a static function is fine, basically its a whole lot of work happening in
this function for a single result, so I'm suggesting splitting off the
calculation for `CanCompareConstraints` into its own function, so you get:
`bool CanCompareConstrants = new_function(...);`
