  Hmmm you might read the free online book, i'm going through it 
and finding it useful so far as a refresher.

  Since the forum is text only, i like to use bbcode as [code] 
blocks (if there's a preferred method, I haven't one). So:

[code]
  auto pi = 3.14159;
[/code]

  hmmm... You'd best be allocating the reference directly on the 
array, you should be able to add to it.

[code]
  handles ~= UR(41);
[/code]
