In the curly braces after any, you must specify a code that returns true or false. $line_number returns false only in the first iteration of the loop when it's zero, and stays true afterwards. Moreover, you don't need $line_number, you already have the $li variable that can serve its purpose: 
#!/usr/bin/perl
use warnings;
use strict;

use List::MoreUtils qw{ any };

my @line_numbers = (1, 2, 5, 6, 9, 10, 18, 19, 23, 24, 25, 30, 31, 33)
+;

for my $line_number (1 .. 35) {
    if (any { $_ == $line_number } @line_numbers) {
        print "$line_number :\n";
    }
}

But for the same output, you can just use 

print map "$_ :\n", @line_numbers;

Instead of the for loop. 

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
