Thanks, added a note to that effect.

Correct. It is one of the first things I wrote, and it definately
needs updating. I now believe the toks array should accept and return
token list tables (instead of lua strings), and there should be helper
functions to_string() and to_tokenlist() for going back and forth.
That needs a bit of (not-yet-done) programming, but it is not hard at

Precisely the above str_toks reference. I've changed the wording in 
manual a bit.
