I'd guess that 'x' is the most appropriate template char. Extracted from
`interactive's docstring:

  x -- Lisp expression read but not evaluated.

Or you don't provide a string description to `interactive'. Then you
have full control over the user input (for example, if you have a
more concrete idea about how your list's members should look like:
you didn't say anything about that part :-)
