for my $ind ( 0 .. $#bb ) {
say "ind is $ind";
}
And to answer your question, it's the maximum you can have. If you want multiple iterators, they necessarily have to be external to the array.
For example, in C#, you have to create an external iterator.
using ( var enumerator = list.GetEnumerator() ) {
while ( enumerator.MoveNext() ) {
var item = emumerator.current;
// ...
}
}
Nothing stops you from doing the same in Perl.
Now, C# does have syntactical sugar that makes this cleaner.
for ( var item in list ) {
// ...
}
Again, nothing stops you from doing the same in Perl.
If no one's done it, I guess it's not that useful. (I'm not saying noone's done it. I have no idea.)
