hi,

As we read in Damian Conway- Perl6-notes, there will by a var-iterator that
can be used to see how many times the cycle has been "traversed" i.e.

foreach my $el (@ary) {
   .. do something ....
     print $#;  <--- print the index (or print $i )
}

shall we have :

foreach my $el (@ary) {
     print $# if $#.first();  <--- print the index on the first iteration
i.e. 1
   .. do something ....
     print $# if $#.last();  <--- print the index on the first iteration
i.e. $#ary
};

note : we can iterate on something else not only array
OR :

foreach my $el (@ary) {
     print $# if first;
   .. do something ....
     print $# if latest;
};
