in thread Hashes: Deleting elements while iterating

Put in a print statement in the "faulty" for-loop and you'll see immediately what goes wrong. 

foreach $key (%index){
       print "deleting $key\n";
#      delete $index{$key} if ($key =~ /$test.+/);
}

    Yes, indeed it does help. Thanks.

    So, after digging more in my book, I see now that i needed a keys function in it. All is well again. 

    foreach $key (keys %index) {
       print "deleting $key\n";
#      delete $index{$key} if ($key =~ /$test.+/);
}

    Some of us just need learn the hard way!

    Update: I see now an earlier reply by chromatic, mentioned needing the keys function as well, but it was lost on me at that moment. Sorry.
