you are even referring to two different @_ arrays explicitly. The one that passes the parameters into the subroutine and the global one that you use to store your data.

:) There is only one @_ and it is "super global" that is anytime you write @_ its always @_ (its always @main::_ ) regardless of package

Symbol isn't exactly authoritative but it does show this 

$ perl -MSymbol=qualify -le " print qualify($_,q/Fooo/) for qw/ ARGV S
+TDOUT STDERR _ AHOY /
main::ARGV
main::STDOUT
main::STDERR
main::_
Fooo::AHOY

pervar says: Perl identifiers that begin with digits, control characters, or punctuation characters are exempt from the effects of the package declaration and are always forced to be in package main ; they are also exempt from strict 'vars' errors. A few other names are also exempt in these ways: ENV STDIN INC STDOUT ARGV STDERR ARGVOUT SIG
