Is there a tricky way to initialize a hash based on a string (or array), where the keys are each value listed in the string and the corresponding values are their numbers in the sequence (or array index)?

I´m sure there is a better way than the for in:

my $tokens = "32,15,4,72,13,28,14";
my %code;
my $i = 0;
for my $t (split(/,/, $tokens)) {
  $code{$t} = $i++;
}
