You're welcome. ;-)
This effect means that:
don't do the same thing either, whereas from the 'overloaded operator' point-of-view *as far as I can tell* they do the same thing. The 'unless' statement runs the overloaded '!' subroutine of the class in question, as opposed to doing a 'bool' conversion on the class and doing a logical NOT on the result of that, which is the other thing it *might* be expected to do.
I just wrote a class to check this. It claims that everything is true (especially the lies), and is called 'Garak', ;-)
