Hi,

I am confused by the following piece of code:
#!/usr/local/bin/perl -w

use strict;

use constant TESTVALUE => 1;

my %hash1 = (TESTVALUE    => "OK");
my %hash2 = (123        => TESTVALUE);

my $hashValue;

# Try 1
$hashValue = %hash1->{1};
# Try 2
$hashValue = %hash1->{TESTVALUE};
# Try 3
$hashValue = %hash1->{%hash2->{123}};

Only try 2 returns the desired result "OK" from hash1. Why not try 1 and try 3? Am I missing something?

TIA
