title: Number of items stored in Bucket list
body: <p>I was wondering how to get the number of items stored in a TBucketList. As far as I can see there is only the number of buckets and the bucket array available, so all I can think of is</p>
  
  <pre><code>Count := 0;
  for I := 0 to BucketList.BucketCount - 1 do
    Inc (Count, BucketList.Buckets [I].Count);
  </code></pre>
  
  <p>That does work but it seems odd to me, that I have to iterate through all buckets to find the number of items stored - something that is probably needed very often.</p>
  
  <p>Am I missing another possibility? Or is there a reason why this container class does not provide a Count member like the other containers?</p>
  
  <p>Thanks!</p>
