if nobody beats me to it I'll write a sentence or 2 to insert into perlvar to suggest using $h{(),@a} when you want to get the multiple emulated dimensions out of an array. I use the feature often and find it handy. The syntax is nice; I would not want to throw away $; without replacing it with something else that will understand $h{(),@a} as a multidimensional hash key. And I can't OTTOMH produce one that would not involve eval-stringing a joined map result.
