At the moment yes.  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.

Bruno
