We agree that this is not very LaTeX3-like. The current plan is to introduce a higher-level function to convert comma lists and sequences to nicely setup lists of the form "item1, item2, item3, and item4". \clist_use:Nnnn <clist var> { <separator for two> } { <separator in general> } { <last separator for more than 2> } For instance, \clist_use:Nnnn \l_my_clist { ~ and ~ } { , ~ } { , ~ and ~ } would give item1 % if the clist had only one item item1 and item2 % if the clist had two items item1, item2, and item3 % for 3 items or more. We have not yet decided whether to add this function yet. Since \clist_use:N was not used in TeXLive 2011 (apart from our own l3doc), deciding this seemed less urgent than other issues. Regards, Bruno
