Thanks for the suggestion. I was thinking Array::Findone myeself.

While there is a findfirst function, the difference is findone knows where it is within an array, so on subsequent calls it gives subsequent elements. "sort-of" like a closure without the closure. Basically it knows from the source code context what array you are using. 

# It's does something similar to this.
sub elementer(&\@;$$) {
    my ($coderef,$arrayref,$start_index,$end_index) = @_;

    
    $start_index = 0 unless $start_index;
    $end_index = $#{$arrayref} unless $end_index;

    return sub {
            return if $start_index > $end_index;
            for  (; $start_index <= $end_index;$start_index++){
                
                $_ = $arrayref->[$start_index];
                if (&$coderef){
                    $start_index++;
                    return wantarray ?  ($_ ,($start_index -1 ) ) : $_
+;
                }
            }    
        }


}


my @nums = (1..1000);
my $find = elementer { "$_" =~m/5$/ } @nums ;

while (my $found = $find->() ) {
     # ... do something with each match
    print $found,"\n";
}
