Here is one (inelegant) approach which might work for you:

#! perl
use strict;
use warnings;
use Capture::Tiny ':all';

my ($stdout, $stderr, @result) = capture
{
    interface_control();
};

my    @lines = split "\n", $stdout;
print $lines[0], "\n";

sub interface_control
{
    my @r;
    get_handles(\@r);
    print "blah blah for $_\n" for @r;
}

sub get_handles
{
    @{ $_[0] } = 11 .. 13;
}

Output:

14:00 >perl 1204_SoPW.pl
blah blah for 11

14:00 >

Update: Removed unnecessary parentheses from print statement, plus a blank line.

Hope that helps,
