Sure, it returns a `llvm::iterator_range<shadow_iterator>`, which is just a
range adaptor for a pair of iterators. It's not a "collection of iterators",
it's a "collection, defined by a pair of iterators". If you iterate over it
using a range-based for loop, you get whatever is pointed by the iterators, not
iterators.
