perl - HASH element from an object's return in a single string -

i have module module.pm function gethash() returns, guessed, hash of data)). know how element form hash, using standard model:

use module; $m = new module; %hash = $m->gethash(); print $hash{needed_element's_key}; 

everything ok. if need write 2 last strings in single string without initializing new hash (and occupying memory whole hash, using 1 element)?

is possible somehow? like, say, $m->gethash()->{needed_element's_key}; of course, given example not work. suggestions? thanks!

it's impossible return hash. subs can return list of scalars. assigning list of scalars existing hash my %hash , getting element of hash.

you disguise fact creating new hash using anonymous hash:

my $val = { $m->getkeyvalpairs() }->{$key}; 

alternatively, custom filter more efficient:

sub find_val {    $target_key = shift;    while (@_) {       $key = shift;       $val = shift;       return $val if $key eq $target_key;    }     return undef; }  $val = find_val $key, $m->getkeyvalpairs(); 

but best option have method return reference hash instead. then, wouldn't have perform wasteful activity of creating hash. you'd use following:

$m->gethashref()->{$key}
