Yes, it is. You can declare v-strings either by prepending a "v" to one or more dot-separated integers, or just 3 or more dotted integers. http://austin.pm.org/presentations/march2000/raty/vstrings.html I believe the latter syntax is deprecated, though; it turned out to be confusing and pretty roundly hated. It's preferred to use the v syntax.
