I don't really mind the term "lexeme", but I've wondered why the
existing tokens/2 function wasn't simply updated to work the way
lexemes/2 works.

If we needed a new function, it seems the name "tokenize/2" might
have been an easier mental adjustment.

But anyway, naming things is hard and... meh. For me the unicode
enhancements are a big enough deal that I could *almost* care less
what they are called.

That said, who isn't going to open a new language's string lib and
expect to find things called "split" "tokenize"/"tokens", "clean",
"right", "left", "pad", etc.?
