you can do it with a hash ref:
Code:
my $hashref = {};
$hashref->{var1} = 'val1';
my $var1 = $hashref->{var1};
$hashref->{$var1}= 'val2';
my $var2 = $hashref->{$var1};

print "KEYS:\n";
foreach my $key (keys %$hashref)
{
	print "key=".$key."\n";
}
print "\nVALUES:\n";
print "var1=".$var1."\n";
print "var2=".$var2."\n";

this results in
Code:
KEYS:
key=var1
key=val1

VALUES:
var1=val1
var2=val2
