What do you mean? [ ] and test are functionally identical.
In my code example I have added quotes around the variables, for increased robustness.

hi,
In bash,
$ bind -P | grep yank-last
yank-last-arg can be found on "\M-.", "\M-_".
this allows me to press ALT key and the period (.) to yank the last argument of
the previous command line into the current command line.
How can I get the same behavior in zsh ?
Thanks ... (0 Replies)

test::identity
Test::Identity(3pm) User Contributed Perl Documentation Test::Identity(3pm)
NAME
"Test::Identity" - assert the referential identity of a reference
SYNOPSIS
use Test::More tests => 2;
use Test::Identity;
use Thingy;
{
my $thingy;
sub get_thingy { return $thingy }
sub set_thingy { $thingy = shift; }
}
identical( get_thingy, undef, 'get_thingy is undef' );
my $test_thingy = Thingy->new;
set_thingy $test_thingy;
identical( get_thingy, $thingy, 'get_thingy is now $test_thingy' );
DESCRIPTION
This module provides a single testing function, "identical". It asserts that a given reference is as expected; that is, it either refers to
the same object or is "undef". It is similar to "Test::More::is" except that it uses "refaddr", ensuring that it behaves correctly even if
the references under test are objects that overload stringification or numification.
It also provides better diagnostics if the test fails:
$ perl -MTest::More=tests,1 -MTest::Identity -e'identical [], {}'
1..1
not ok 1
# Failed test at -e line 1.
# Expected an anonymous HASH ref, got an anonymous ARRAY ref
# Looks like you failed 1 test of 1.
$ perl -MTest::More=tests,1 -MTest::Identity -e'identical [], []'
1..1
not ok 1
# Failed test at -e line 1.
# Expected an anonymous ARRAY ref to the correct object
# Looks like you failed 1 test of 1.
FUNCTIONS
identical( $got, $expected, $name )
Asserts that $got refers to the same object as $expected.
