You may get this behavior with List::MoreUtils. The following presents two such solutions. They are not very pretty, but they work.

First, you may generate an index array with [ 0 .. $#array ] and use each_arrayref/each_array to produce an iterator that loops over possibly many arrays at a time. 

use List::MoreUtils qw( each_arrayref );

my @a = qw( a b c d e );
my $each = each_arrayref( [ 0..$#a ], \@a );

while ( my ($idx, $v) = $each->() ) {
    print "$idx: $v\n";
}

Second, you may use the documented behavior that the iterator returns the current index when given arguments ('index'). 
use List::MoreUtils qw( each_array );

my @a = qw( a b c d e );
my $each = each_array( @a );

while ( my $v = $each->() ) {
    my $idx = $each->('index');
    print "$idx: $v\n";
}
