the life of the script. However, mentioning C</o> constitutes a promise

If the PATTERN evaluates to the empty string, the last

in a bit vector.
+=head2 Strings of Character
+
+A literal of the form C<v1.20.300.4000> is parsed as a string composed
+of characters with the specified ordinals. This provides an alternative,
+more readable way to construct strings, rather than use the somewhat less
+readable interpolation form C<"\x{1}\x{14}\x{12c}\x{fa0}">. This is useful
+for representing Unicode strings, and for comparing version "numbers"
+using the string comparison operators, C<cmp>, C<gt>, C<lt> etc.
+
+If there are more than two dots in the literal, the leading C<v> may be
+omitted.
+
+Such literals are accepted by both C<require> and C<use> for doing a version
+check. The C<$^V> special variable also contains the running Perl
+interpreter's version in this form. See L<perlvar/$^V>.

=head2 Integer Arithmetic
By default, Perl assumes that it must do most of its arithmetic in
The non-standard modules SSLeay::BN and Math::Pari provide
equivalent functionality (and much more) with a substantial
performance savings.
