mapping

Hi folks.

I have a array like this:

my @arr = ("Field3","Field1","Field2","Field5","Field4");

Now i use map like below , where /DOSOMETHING/ is the answer am seeking.

my %hash = map {$_ => **/DOSOMETHING/** } @arr

Now I require the hash to look like below:

Field3 => 0
Field1 => 1
Field2 => 2
Field5 => 3
Field4 => 4

Any help?
