Adding in -MO=Deparse: 
perl -MO=Deparse -plwe "$h{$_}++ } for (sort {length($a) <=> length($b
+) } keys %h) {"

BEGIN { $^W = 1; }
BEGIN { $/ = "\n"; $\ = "\n"; }
LINE: while (defined($_ = <ARGV>)) {
    chomp $_;
    ++$h{$_};
}
foreach $_ (sort {length $a <=> length $b;} keys %h) {
    ();
}
continue {
    print $_;
}

The -p option wraps the script in a template equivalent to the following: 
while (<>) { your code here }
continue { print $_ }

If your code happens to have a closing curly, you can do all kinds of interesting things. My favorite was Abigail-II's substitute for wc, to count lines: 
perl -wlpe '}{*_=*.' filename
