+=head2 Plain "0" string now treated as a number for range operator
+
+Previously a range C< "0" .. "-1" > would produce a range of numeric
+strings from "0" through "99", this now produces an empty list, just
+as C< 0 .. -1 > does.
+
+This was due to a special case that treated strings starting with "0"
+as strings so ranges like C< "00" .. "03" > produced C< "00", "01",
+"02", "03" >, but didn't specially handle the string C<"0">.

+This was disallowed because it causes unexpected behaviour, and no-one
+could define what the desired behaviour was.
