Moose::Autobox::Array(3)				User Contributed Perl Documentation				  Moose::Autobox::Array(3)

NAME
Moose::Autobox::Array - the Array role SYNOPOSIS
use Moose::Autobox; [ 1..5 ]->isa('ARRAY'); # true [ a..z ]->does('Moose::Autobox::Array'); # true [ 0..2 ]->does('Moose::Autobox::List'); # true print "Squares: " . [ 1 .. 10 ]->map(sub { $_ * $_ })->join(', '); print [ 1, 'number' ]->sprintf('%d is the loneliest %s'); print ([ 1 .. 5 ]->any == 3) ? 'true' : 'false'; # prints 'true' DESCRIPTION
This is a role to describe operations on the Array type. METHODS
pop push ($value) shift unshift ($value) delete ($index) sprintf ($format_string) slice (@indices) flatten flatten_deep ($depth) first last Indexed implementation at ($index) put ($index, $value) exists ($index) keys values kv each each_key each_value each_n_values ($n, $callback) List implementation head tail join (?$seperator) length map (&block) grep (&block) Note that, in both the above, $_ is in scope within the code block, as well as being passed as $_[0]. As per CORE::map and CORE::grep, $_ is an alias to the list value, so can be used to modify the list, viz: use Moose::Autobox; my $foo = [1, 2, 3]; $foo->map( sub {$_++} ); print $foo->dump; yields $VAR1 = [ 2, 3, 4 ]; reverse sort (?&block) Junctions all any none one meta print say BUGS
