| Since LISTs can contain anything that returns array values, you could say
| 
| 	$time = (stat($file))[8];
| 
| That could be parsed unambiguously, methinks.
| 
| It would in fact be a slice operator, so you could say
| 
| 	@days = ('Sun','Mon','Tue','Wed','Thu','Fri','Sat')[$beg .. $end];
| 
| What think?

Yeah, yeah, yeah.  Supercool!  I'm thinking of how to use that in my
signatures already! :-)
