also the functionality is there with string-join (at the cost of an extra
pair of brackets):


string-join((author, title, subject))

will first flatten the three sequences of authors titles and subjects
into one sequence and then munge them all in to one string.


That's not to say it's not confusing. It'll no doubt keep us busy on this
list long after for-each-group has killed off all questions about
muenchian grouping:-)
