   guile> (string-tokenize "stan-henry" (char-set #\-))

   --> as documented, this should return ("stan" "henry").

perhaps you aren't seeing this documentation:

  - Scheme Procedure: string-tokenize s token_set start end
      Split the string S into a list of substrings, where each substring
      is a maximal non-empty contiguous sequence of characters from the
      character set TOKEN_SET, which defaults to `char-set:graphic' from
      module (srfi srfi-14).  If START or END indices are provided, they
      restrict `string-tokenize' to operating on the indicated substring
      of S.
the token set defines the charset of the tokens, rather than of the
delimiter; you need to invert it to get the desired behavior.  e.g.:

  guile-tools --source split-string-no-nulls | fgrep -A5 '. sep'
