( #3333=superdoc: print w/ replies, xml ) Need Help??

If you insist in using a range-/list-op, you could do:

if ( grep { $ref == $_ } 1..8 ) { ... }
But personally, I would rather use something like
if ( $ref >= 1 and $ref <= 8 ) { ... }
or maybe
if ( $ref =~ /^[1-8]$/ ) { ... }

Update: (in response to OP's reply below) With a modern Perl, you could use given/when:

use v5.10; use strict; use warnings; my @tests = qw(1 9 17 25 33); my $range_25_32 = [25..32]; # alternatve, maybe(?) faster for my $ref ( @tests ) { given ( $ref ) { when ( [1..8] ) { say "A $ref" } when ( [9..16] ) { say "B $ref" } when ( [17..24] ) { say "C $ref" } when ( $range_25_32 ) { say "D $ref" } default { say "ELSE $ref" } } }
Output:
A 1 B 9 C 17 D 25 ELSE 33
With the given ranges in the example below, some bitwise operators might also work.
