The use of relational operators (
with strlst values has been clarified somewhat in version 7.
While usage with strlst is discouraged - as strlst values
are set-like but the relational operators are for scalars - a
strlst relational expression will now generally compare the two
strlsts as atomic entities, promoting the non-
side if present (as a single item). Version 6 behavior is restored if
<vxcp compatibilityversion> is set to 6.
