vi mode in readline

morgon has asked for the wisdom of the Perl Monks concerning the following question:

Hi, this works but seems to use the emacs editing mode when Term::Readline::Gnu is installed:

use strict;
use Term::ReadLine;

my $term = Term::ReadLine->new('a');
print "you entered: " .  $term->readline("Enter something: ");

Is there a way to use vi-mode?

Many thanks!
