-----------------------------------+------------------------------------
 I'm trying out tabular as replacement for csv-abnf and found that it
 supports associating column names with rows. However if I specify both
 column-names (no matter whether it's set to the undocumented `'header`
 option to automatically derive them from the first line or a list of
 strings to explicitly specify them) and return-names, I get an inscrutable
 backtrace:

 {{{
 (call-with-input-file "test.csv"
   (lambda (in)
     (let ((reader (csv:reader* in column-names: 'header return-names:
 #t)))
       (write (reader))
       (newline))))
 }}}
