Finding member names of a member type

   Is it possible to create a list of the names that comprise a member
type? For example, suppose I have defined

	(deftype languages () '(member ada pascal c cobol))

what I want is something like

	(setf lang-list (member-names 'languages))

The reason behind this is that I require a function that will display
each of the possible languages and ask the user to select one.

If this is not possible, can someone suggest a way of doing this, bearing
in mind that the list of languages in the type will depend on which user
is currently running the program.

Thanks in advance,
