I<n>-th subpattern, or undef if the subpattern did not match.
Thus after a match against $_, $& coincides with C<substr $_, $-[0],
-$+[0] - $-[0]>. Similarly, C<$>I<n> coincides with C<substr $_, $-[>I<n>C<],
-$+[>I<n>C<] - $-[>I<n>C<]> if C<$-[>I<n>C<]> is defined, and $+ coincides with
-C<substr $_, $-[$#-], $+[$#-]>. One can use C<$#-> to find the last
+$+[0] - $-[0]>. Similarly, $I<n> coincides with C<substr $_, $-[n],
+$+[n] - $-[n]> if C<$-[n]> is defined, and $+ coincides with
+C<substr $_, $-[$#-], $+[$#-] - $-[$#-]>. One can use C<$#-> to find the last
matched subgroup in the last successful match. Contrast with
C<$#+>, the number of subgroups in the regular expression. Compare
with C<@+>.
