    Implement \tl_set_eq_clist:NN to change type but not data (see #786)
    
    In l3keys there are various places where one has a clist variable
    and one wants to store it in a tl.  I wouldn't mind using
    \tl_set_eq:NN (tl var) (clist var), with the thought that the
    (clist var) is in particular a tl var, but others may disagree.
    We should discuss.
