Perl has so many weird behaviours (or behaviours which appear to be weird before you understand them...), exceptions and details.
When I think of "Perl's tiny details", the first thing that pops in my mind, ever since I've read about it, is the difference between \(@array,@brray) and \((@array),@brray). (And I have no idea why;)

So..What do you think of?What's your favourite "detail"?

P.S: Trying to Deparse the two, I get the same output...Seems like a bug to me... Or am I wrong?
