Expand description
An iterator-like for ValueList
An instance of this can be easily obtained from IT: Iterator<Item: ValueList>: that would be
BatchValuesIteratorFromIterator<IT>
It’s just essentially making methods from ValueList accessible instead of being an actual iterator because of
compiler limitations that would otherwise be very complex to overcome.
(specifically, types being different would require yielding enums for tuple impls)
