I wonder if it allows:
$vars = fun()['2']['4'];
or
$vars = fun2(fun()['2'])['3'];
Similar syntatic sugar has been in Perl since dirt was formed. In fact, I have been asked variants of this question in job interviews just to gauge much experience I had with the language. For example, if constructing today's date is the desired purpose:
Code:
#!/bin/env perl
my ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst) = localtime(time);
printf "%d-$mon-$mday\n", $year + 1900;
...can be reduced to the following which eliminates a lot of extraneous clutter:
Code:
#!/bin/env perl
my ($year, $mon, $mday) = (localtime time)[5,4,3];
printf "%d-$mon-$mday\n", $year + 1900;
FWIW.
