Thanks, IO::Tee gets me a little bit closer 
#!/usr/bin/perl -w
use strict;
use warnings;
use IO::Tee;
use IO::File;

my $stdout;
open(my $fh, "+<", \$stdout); 
my $tee = new IO::Tee(\*STDOUT, $fh);
print $tee `echo Test`;
print $stdout;

However I am actually trying to capture STDERR, so this code isn't that useful to me. I have tried IO::CaptureOutput but I can't get that working. Note apologies, as I know that this (capturing STDERR to local variable as well as directing to file) has been covered many times before perlmonks and elsewhere, but I haven't come across a definitive solution - I was hoping that TeeOutput would be the answer, I guess not.
