You can also check my Can you use string as a HASH ref while "strict refs" in use? for a hard to debug behaviour you can get without `strict 'refs'` (and how to get the same confusing behaviour with strict, too). `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]
