It is correct, as of C++20. Proxy iterators are first-class citizens, as
of the ranges concepts work. I used that reference type on purpose, and I
refer to that later in the docs. Also, this is copy-paste from Boost.Text
(proposed), which uses that exact iterator with a "char const" reference
type.
