Assuming you already have a bunch of hashrefs you need to corral, I would consider something like this:
>perl -wMstrict -le
"my @vals =
qw(val1 val2 val3);
my ($hr1, $hr2, $hr3) = ({a => 1}, {b => 2}, {c => 3});
my @h_refs = ($hr1, $hr2, $hr3);
;;
die 'arrays not same size' if @h_refs != @vals;
;;
$h_refs[$_]->{k} = $vals[$_] for 0 .. $#vals;
;;
use Data::Dumper;
print Dumper $hr1, $hr2, $hr3;
"
$VAR1 = {
'k' => 'val1',
'a' => 1
};
$VAR2 = {
'k' => 'val2',
'b' => 2
};
$VAR3 = {
'c' => 3,
'k' => 'val3'
};
