More things that you can put inside @{[]} .

#!/usr/bin/perl -w use strict; use Data::Dumper; my $complex = { a => [ 1, 2, 3 ], b => [ { x => 1, y => 2, z => 3 }, 'alpha', [qw(even more nested ) +] ], c => { one => [qw(more value)] } }; # a function result print "@{[ eval 'Data::Dumper->Dump([$complex ],[q{complex} ])' ]}"; # a list print "@{[ ('aa'..'at') ]}\n"; # a list generated by a Regex print "@{[ 'hello Perl!' =~ /./g ]}\n"; # a list from a filehandle { local $/; print "@{[ <DATA> ]}\n"; } # (update) or simply print "@{[ <DATA> ]}\n"; # a list from globbing print "@{[ <*.pm> ]}\n"; __DATA__ This is text from DATA

This would be the resulting output (The *.pm files depend on your current dir, of course).

$complex = { 'a' => [ 1, 2, 3 ], 'b' => [ { 'x' => 1, 'y' => 2, 'z' => 3 }, 'alpha', [ 'even', 'more', 'nested' ] ], 'c' => { 'one' => [ 'more', 'value' ] } }; aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar as at h e l l o P e r l !
