Hi guys !

A simple one. How can I convert an array of n elements to a hash with those n elements as keys? (the values are not important to me).

Second one. I have to run on the above hash as follows:

while (1) {
  for $key (keys(%myhash)) {
    if (&isPassTest()) {
      delete($key);
    }
  }
}

like that I run on a decresing hash %myhashtill every element passes the test and the hash is empty. Will it work or removing elements while running on the hash can cause problems of some sort?

Thanks.
