Many thanks, brothers, for your suggestion.
I'm sorry for my not clear question. I'd like to define it more exactly.
I have a package with defined constants: 
package C;

my $consts = { CONST1 => 1,
               CONST2 => 2,
               CONST3 => 3,
               CONST4 => 4,
                . . . 
             };
use overload '``' => sub { return $const_values{shift} } ;

# All constants can be accessed as by using AUTOLOAD
sub AUTOLOAD {
    no strict 'refs', 'subs';
    if ($AUTOLOAD =~ /.*::([A-Z]\w+)$/) {
      my $const_name = $1;
      *{$AUTOLOAD} = sub {return $const_values{$const_name}};
        return $const_values{$const_name};
    }
    return undef;
}
 
1;

In may script I have some choises: 
if($status == C->CONST1) { print "1" }
elsif($status =~ /(2|3)/ { print "2 or 3" }
else                     { print 'Something' }

I'd like to use my constants intead of numbers: 
if($status == C->CONST1) { print "1" }
elsif($status =~ /(C->CONST2|C->CONST3)/ { print "2 or 3" }
else                     { print 'Something' }

but it doesn't work. Of course, I know that I can write like this: 
$status == C->CONST3 or $status == C->CONST3

But I wouldn't like to do it.
Any suggestion will be helpful.
