I have a list containing structures. How can I sort the list on one of
the structure-fields using the sort-function? My structure has a :name
field on which I wish to sort the list. 

Thanks,

Ernest

(sort list-of-mystructs #'string-< :key #'mystruct-name)

--- or something like it.

(defstruct foo
  name)

(sort foos #'string< :key #'foo-name) ; not tested
