Could you explain what the impact of this is? Is the concern that we'll have a different result between calls to the hidden function call, or that it's somewhat wasteful to call it multiple times, or something else? I think I and other people understand that it can be a call, but don't see why that matters in this instance. -- Alan Shutko <[EMAIL PROTECTED]> - In a variety of flavors!
