Need Help??

This being a simple case, I thought the typical way to do it would be in the form:

sort 
{ 
  (defined($a) <=> defined($b))  
  || 
  ($a cmp $b) 
}

Nice! I was worried that <=> can't handle "" without warnings, but that's not the case here. :) (empty string is the false value returned from `defined(undef)` ) EDIT Forget it, I'm getting old ... false is a dual var which resolves to 0 in numeric context.
