What about the end/length of a token? Token.str.length would give the
number of bytes (code units?) instead of the number of characters (code
points?). I'm not entirely sure what's needed when, for example, doing
syntax highlighting. I assume you would know the length in characters of
a given token internally inside the lexer?
