Assuming you are addressing a senior enjinere, not a neophyte, yes I could tell 
the difference between an interrupt and the rest of my program running. It has 
major side-effects; I stuck the sample code at the top of my current project.

Curiously, this is what the original code was doing:

begin
   raise Interrupt
rescue Object
   p $!.class # sez Interrupt
end

I didn't catch it either - 'raise' raises the given object, which here was class 
Interrupt, and the metaclass itself of course does not inherit StandardError.

Try:

begin
   raise Interrupt.new('L.A. woman')
rescue
   p $!.class
end

That does not invoke the rescue, and does clobber the program, all for the 
correct reasons. And rescue Interrupt catches it.
