NAME
Ref::List - Punctuation-free dereferencing of arrayrefs and hashrefs
VERSION
version 0.002
SYNOPSIS
use Ref::List qw(list);
my $data = {
countries => [
{ name => 'Bulgaria', language = 'Bulgarian' },
{ name => 'Germany', language = 'German' },
],
};
print $_->{name} for list $data->{countries};
DESCRIPTION
This tiny module exports a single function, list
, which dereferences the arrayref or hashref passed to it as an argument. list $argument
is basically a synonym for @{$argument}
, but is less awkward when $argument
is a longer expression part of a nested data structure and may appeal to people with a dislike of punctuation overuse.
As of perl 5.14 you should be using the built-in values
function instead.
FUNCTIONS
list (HASHREF|ARRAYREF)
Given a hash or array reference, dereference it and return its contents as a list. If the argument is undef
, returns undef
.
