Given the fact that

I was surprised that

    static assert("é".byCodeUnit.length == 2);
    static assert("é".byCodePoint.length == 2);

string already iterates over code points. So byCodePoint doesn't
have to do anything on it, and it just returns the same string
again.

string's .length is the number of code units. It's not compatible
with the range primitives. That's why hasLength is false for
string (and wstring). Don't use .length on ranges without
checking hasLength.

So, while "é".byCodeUnit and "é".byCodePoint have equal
`.length`s, they have different range element counts.
