This will take a few lines of "dirty tricks", as Donald E. Knuth 
explains in The TeXbook (pages 378/379).  There he defines a "set macro" 
{\alpha, \beta, \gamma } and provides a method "\ismember #1\of #2" 
which tests whether a given control sequence is in the set. You will 
have to modify the "\rightappenditem #1\to #2" method somewhere because 
it is for list macros of a different kind.
