Regexp::Common::lingua -- provide regexes for language related stuff.

use Regexp::Common qw /lingua/;

while (<>) {
    /^$RE{lingua}{palindrome}$/    and  print "is a palindrome\n";

Please consult the manual of Regexp::Common for a general description of the works of this interface.

Do not use this module directly, but load it via Regexp::Common.

Returns a pattern that recognizes a palindrome, a string that is the same if you reverse it. By default, it only matches strings consisting of letters, but this can be changed using the "{-chars}" option. This option takes a character class (default is "[A-Za-z]") as argument.

If "{-keep}" is used, only $1 will be set, and set to the entire match.

This pattern requires at least perl 5.6.0.
