`reference` being `char const` in the introductory example doesn't feel correct. `char const` can't be returned from a function (such as `operator*`), top-level qualifiers aren't meaningful for `char`.

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.

Thanks. You should however be aware that both gcc and clang warn on functions returning `const char` with -Wextra. :-)

Huh. Good to know. I guess I should change it to char then. Zach
