Yes, there is a difference in that you get an empty list rather than
an empty value.

One workaround is to add an "AND item.size" condition at the end:

   [% WHILE (item = mylist.splice(0,2)) AND item.size %]

I'll have a think about the implications of changing the vmethod to
return an empty value.  But either way, it'll be something for TT3.
