There isn't much going on here. '$#' followed by a name of an array gives
you the index of the last element. '@' followed by the name of an array,
followed by a list inside '[]' gives you a slice, a list of elements
from the array, indexed by the list found inside the '[]'.
Now, to deal with references, Perl has a rule: where ever you have a
variable (be it simple like $scalar, or complex like $array [index]),
you may replace the name of the variable by a block (delimited by '{}')
whose result is a reference to the appropriate type.
So, @{ }[ ] is just a slice of the array pointed to by the reference inside
the { }, and $#{ } is the index of the last element of the array pointed
to by the reference inside the { }.

Well, I wouldn't go there not even if my company would be paying for me
(or someone else for that matter). The reason I won't go isn't that I
would have to pay lots of money, but that they charge everyone that much.
As for O'Reilly making money on it, I've heard that they actually lost
money the last time (and maybe ever the previous time). That O'Reilly is
making (or trying to) make money out of it is their good right. They are
a commercial company after all, and that's what commercial companies do:
make money. They have employees they need to pay, and I guess they have
stockholders too.
I'm sometimes a bit disappointed that most people don't share my views and
happily pay such high fees (now, if just 1 out of 20 decided to pay the
same amount to the Perlfoundation, wouldn't that be great?), but everyone
is entitled to decide for themselves where to spend their money on.

There might be 3 YAPC's to choose from next year, if Nat manages
to do a YAPC::Winter.
