nemesdani:

You can use slicing to eliminate the redundant calls:

$ cat foo.pl
use strict;
use warnings;
use Data::Dump 'dump';

my %h;
@h{'A', 'B', 'C'} = @{foo()}[0,1,2];
print dump(\%h);

sub foo {
    [3, 2, 1];
}

$ perl foo.pl
{ A => 3, B => 2, C => 1 }

The @h{'A', 'B', 'C'} is a hash slice, and the right uses an array slice. You'll find hash and array slicing described in perldoc perldata.

Update: Fixed link to docs.
